Grab The RSSWhen to use “on” and when to use “in”
Nate asks: What are the proper usages of the words “in” and “on” in a sentence? I often confuse the two. Here are some examples: “The boat is in/on the water,” “We are in/on the planet,” “We’re going to the concert in/on July 1st.”
The use of prepositions in English is frequently idiomatic. General guidelines exist, but be prepared to learn individual expressions in which the preposition does not adhere to the guidelines.
In the case of the prepositions in and on, here are the most usual uses.
In
in mainly denotes “rest at”:
PLACE: He lives in the country. He lives in Chicago. (BUT, He lives at 2300 Wabash Ave.)
TIME: I’ll be there in an hour.
MANNER: The child ran down the steps in tears.
REFERENCE: In my opinion we need a referendum. They are happy in their marriage.
On
on indicates proximity and position above or outside:
PLACE: He sat on the fence.
TIME: He was not thinking well on that occasion.
REFERENCE: He asked my opinion on the matter.
CONDITION: We’ll hire him on your recommendation.
The examples given in the question:
We are on the planet.
We are going to the concert on July 1.
But
We are going to the concert in July.
As for the example about the boat, either is correct, according to what is meant:
The boat is in the water. (As opposed to being on dry land for the winter)
The boat is on the water. (Look at all those boats out there on the water!)
However, it would be unidiomatic to say The ship is in the ocean or in the sea, unless you mean that it has sunk. The ship is on the sea.
Related to the question of when to use in is that of when to use into. While in denotes the state of being “at rest” in a place, or at least being (in a sense) surrounded by something, into denotes motion towards:
The dog jumped into the water.
The children (who were already in the water) jumped in the water.
When deciding whether to use in or into, ask yourself if the person or thing you are talking about is moving from one place to another. If so, use into.
More about prepositions in later posts. Stay tuned!

Very good and clear explanation. I never pick up the difference between these words. Now I think I have got it almost. I wish I knew it before itself. At least I would have got 5 more marks in the English Grammar Exercise. Thanks for the post Maeve.
Honestly Daniel that was one great tip. I myself face the problem of deciding where to use on and where to use in but this post summed it up quite well.
Thanks a lot
I don’t really get the in/on part for TIME, I must use in if im refeering to a specific time, or for the rest of cases, right?
I’m not sure what “temp” is asking. Perhaps a few more TIME expressions will help:
in a minute
in twenty minutes
in two shakes of a lamb’s tail
in a flash
on the Fourth of July
on my birthday
It may be necessary to memorize the more common usages. As I mentioned in the post, prepositional usage is often idiomatic and difficult to pin down.
I don’t think I’ve ever been told what a prepositions is. At least I don’t remember.
Please explain Preposition. Sorry I’m lost at paragraph 2.
Sally, prepositions are words that connect nouns and explain their relationship with other words. Here are some examples:
with
at
by
to
in
for
from
of
on
On an email listserv, someone asked, why do we say:
“In the Army but on a soccer team
In a political party but on a staff”
Any suggestions?
“The use of prepositions in English is frequently idiomatic. General guidelines exist, but be prepared to learn individual expressions in which the preposition does not adhere to the guidelines.”
I am sure if there are any explanations for the cases you mentioned in particular.
Prepositions are simple if you understand that they only function to show relationships. Here is how I explain them to my students (college freshmen and sophmores).
I grab a chair and position myself:
I can be beside the chair, behind the chair, by the chair, and beyond the chair.
I can be in front of the chair, in the chair, and on the chair.
If I have some weird obsession, I could be into the chair.
I can be under the chair and, if somehow melted together and remade, of the chair.
If the chair is one if my parents, I am from the chair. However, I could move away from the chair.
I could walk to the chair. I could stare at the chair. I could move towards the chair.
I could walk around the chair. I could be above the chair. I could feel certain feelings about the chair.
I could make many more examples. However, that’s not the point.
Regarding the question, the word in denotes that the noun is consumed by the object of the preposition . The word on denotes that the noun is above or atop.
I still don’t get the
Great timing–I just heard a clip of Joe Biden on NPR in which he used “on” when he meant “in.”
I’ve never personally experienced any confusion about On and In, but a friend of mine makes me laugh with her usage, which I suspect is dialectic. If she is seated indoors without benefit of chair or other support, she claims to be sitting “in” the floor.
It always triggers a joke from my husband about a man who is instructed to “Get on the plane.” The man’s response: “Forget that–you get on the plane! I’m getting in the plane.”
Is it “We participated in a field trip.” or “We participated on a field trip.”?
Roswell,
“participated in a field trip”
But you’d “go on a field trip.”
What about these:
“We will go to the beach on Monday” or “We will go to the beach Monday”?
“Monday mom baked a pie” or “On Monday mom baked a pie”?
Is it: “his picture was on the paper” or “his picture was in the paper”
His picture was in the paper. (if the picture was printed in the paper.)
If a photo just happened to be lying around, it might end up “on the paper”!
When did the rule about ending the sentence with a preposition change? It’s always been one of my pet peeves (in written word more than spoken) because we learned it was wrong in high school grammar…. but now I’m reading that it’s acceptable?
Annette,
Your question deserves a post of its own. Stay tuned.
My question is about using into and in to. When you are talking about someone who has committed a crime, do they turn themselves “into” the police, or in to the police? Is there a difference? The first one always makes me think of the person as a magician.
Fabgrandma,
The wanted persons would turn themselves in to the police.
They would jump into the water.
See my article on http://www.dailywritingtips.com/me-myself-and-i/
Hello. I understand the correct forms are “in May” and “on May 3rd”, but I can not decide between “In December 2007” and “On December 2007”.
Carlos,
You would use “on” only if the day as well as the month is specificed:
Ex.
I visited Paris in December 2007.
On December 3 (or “on December 3, 2007″), I went to the top of the Eiffel Tower.
Thank you very much… I’ll follow that tip.
My daughter will be going to college in two years from now. Is this grammatically correct. Or the sentence should be without ” in”
Hi there! I too struggle a lot on how to use “on” and “in” in a sentence,don’t know if “in a sentence is correct”,does it?. Until now I’m still confuse, but at least I know now that it is idiomatic and there is a general guidelines exist on using them.. By the way does anyone knows how to use has, had, and have? I know their meanings but sometimes I just don’t know when to use them, like for example; I have done that or I had done that, I know that “had done that means I already did it, but what about “have done”?Like most of the time people uses “have”even though I think “had” is more appropriate to use beacause they are talking about the past. I hope you guys can contribute facts and ideas towards my inquiries. Like everyone else I like to uprgrade my grammar. Thanks.
how about this: “The motivation for this lies IN the need” or is it “The motivation for this lies ON the need”? (I just capitalized IN and ON to stress my point)
“The wanted persons would turn themselves in to the police.”
I understand how people get confused as to when to use “into” and “in” here. There shouldn’t be any confusion once you know the verb is “turn in”, not “turn into”? Correct me if I’m wrong.
They turned themselves in. To whom? To the police. English as a second language here so I could be wrong.
I too get laughed at at the incorrect usage of “in” and “on”. Even after reading the explanations above, I don’t get them as they don’t make sense all the time for me. Spanish as a first language here.
Yoni, here is my try. Not a grammar guru though.
Have = present
Had = past
Done = past participle
1. Hey Mark, have you done what I asked you to do?
1. Yes Louis, I have done what asked me to do.
2. Hey Mark, you told me you had (THEN) done what I asked you to do!
2. Yes silly, I had told you yesterday that I had (THEN) done what you asked me to do. What’s wrong with you man!
If you are a Spanish speaker,
Have = he, has, ha, han, hemos (yo he hecho, conjuga el resto)
Had = habia, habias, habiamos, habian (yo habia hecho, conjuga el resto)
Anything I’m getting wrong please let me know.
Ram,
My daughter will be going to college in two years from now.
You can get away with the “in.” I would omit it and say My daughter will be going to college two years from now.
Yoni,
You asked for help, so I’m going to point out more than one thing here.
1. “in a sentence” is correct.
2. I don’t know if “in a sentence” is correct, does it? should be I don’t know if “in a sentence” is correct, is it?
3. I’m still confuse. (the “ed” is necessary I’m still confused.)
4. “have” and “had”: the use of these helping verbs to form past tenses is explained: here. The main thing to remember is that “had done” describes an action that took place before some other action in the past. Ex. I had dropped the crate before I heard the warning.
Toto,
Good tip. “turn in” is one of those verb phrases so common in English.
If one said “The criminal turned himself into the police,” the meaning would be that the crimnal was a shape shifter!
Migs
“The motivation for this lies IN the need.”
Jm,
I have only two comments on your otherwise excellent examples.
1. Yes Louis, I have done what asked me to do. — I have done what you asked me to do. (just a typo, I expect.)
2. Yes silly, I had told you yesterday that I had (THEN) done what you asked me to do. — The “had” is not necessary in the first clause: “I told you yesterday that I had done what you asked me to do.”
use in with bodies of water, use on with surfaces.
Thank you for correcting me Maeve.
I typed a message “in” his website or “on” his website?
Hi..
am still confused abt IN & ON..
I wrote a test on Arrays. or
I wrote a test in Arrays.
Here Arrays is a topic of the subject.
lavanya,
I wrote a test on Arrays. or
I wrote a test in Arrays.
Two things-
In English we say “I took a test.” “I wrote a paper.”
The test was on Arrays. I wrote a paper on Arrays.
I took a course in Arrays.
What the heck is “Arrays”?
Please tell me if you say:
I have a stain on my shirt or I have a stain in my shirt.
My daughter’s teacher corrected the sentence by putting “in” instead of “on”. I still think it’s “on”.
Please tell me if you say:
I have a stain on my shirt or I have a stain in my shirt.
My daughter’s teacher corrected the sentence by putting “in” instead of “on”. I still think it’s “on”.
R.V.
You’re correct. The idiom is “I have a stain on my shirt.”
Is the teacher an American speaker?
Just checking but I’m correct when I say the following, right?
Nowadays, you’ll find thinner and lighter notebooks available ON the market.
This morning, I went downtown and couldn’t find any fresh bass AT the market. [When would you say IN the market?]
The bank carries heavier losses on its books than we thought.
In his book, the author writes about his troubled childhood.
All the material needed to study for the test can be found in this textbook.
Jim,
You could say “I’m in the market for a new car,” i.e., you are considering a purchase.
Maeve:
What is your background? Are you an English teacher by any chance? Thanks for the tip. BTW, the teacher is not an american teacher.
BTW, the sentence that my daughter wrote was actually:
“The stain on my shirt won’t come off”. Would it still be correct to write it that way or to write it this way: “The stain in my shirt won’t come off” ?
R.V.
You’ve got it! English teacher to the core. I’ve taught at every level from beginning reading to university. One of my undergraduate English degrees is from the University of London and I have a Ph.D. in comparative literature. Currently I channel my need to teach into DWT and my own site http://www.AmericanEnglishDoctor.com/ Please drop in.
R.V.
RE: “The stain on my shirt won’t come off”
In this case it would be possible to say that the stain is IN the shirt, BUT then it would be necessary to say
“The stain in my shirt won’t come out.”
Maeve,
Thanks for answering. Are the rest of the sentences that I wrote correct? What about the following:
Financial derivatives are becoming more widely used IN the stock market these days.
Jim,
The sentences in your earlier post are correct.
“Financial derivatives are becoming more widely used IN the stock market these days.” Yes, this use of “in” is also correct.
What is correct?
“If you need me, I am in the back or I am at the back?”
“If you need me, I am in the back of the garbage bin or I am at the back of the garbage bin?”
“If you need me, I will be in the back or I will be at the back?”
Thank you.
REFERENCE: He asked my opinion on the matter.
IMHO, I think this use is a stretch. I would substitute “about” for “on.”
He asked my opinion about the matter.
More and more it seems that writers have forgotten the word “about” and use “on” instead, a rather annoying tendency.
hi!
Please explain the difference of errands and chores..
I really find this website very helpful for me especially that I am an english teacher here in the Philippines
Errands: Getting things done out of the house. Going to the store, going to wash your car, etc. Doing something out of the house.
Chores: Doing things in the house, like doing laundry, cooking, cleaning the bathroom, paying the bills, etc.
Correct me if I’m wrong.
We are going on vacation. We will go in the car, in the camper, in the truck.
We will go on a plane, on a boat, on a train, on a bus.
this doesn’t help:
use in with bodies of water, use on with surfaces.
nor this: in mainly denotes “rest at”
on indicates proximity and position above or outside.
I wonder if it’s because someone else is driving the plane, boat, train or bus. But the vacationer would be driving the car, camper, truck.
hmmmmm
The question above is possibly because we have to bend to get in a car ect..
We can walk on a plane ect…
That is what I was told anyway..
Correct me if I am wrong.
New to this site but willing to help if I can
Mike, include more details. This is what I think is the correct usage:
“If you need me, I am in the back”
“If you need me, I am in the back of the garbage bin” (if you are inside the garbage bin, in the back of it)
“If you need me, I will be in the back”
Anybody please feel free to correct me, if needed.

I have a doubt. Should we say on October 2008 or in October 2008. I know we use in for months and years (in December, in 2009) but how about the two together. I speak English as a foreign language so I’m not that accurate in using prepositions. :S Thanks for your help
I need your comment because I’m confused what to use “write your answer on the blank” or “write your answer in the blank”
I love you all for your questions and comments ! Maybe I will finally stop thinking I’m a certified num skull, and that error is human. Please do you say your birthday has passed or past? Which one is right? You get a treat if you got it rigth or if you get it right?

Thanks so much Maeve. You are great!
regarding the use of the word ‘in’ and ‘on’. from this two sentences: the nurse observes a nursing assistant providing care on the medical/surgical unit. can we use the word ‘in’ instead of ‘on’ here. how about this; a patient in the outpatient clinic prioritizes patients for evaluation. again can we use the word ‘on’ here. another sample: a patient suffers from a pulmonary embolism in the recovery room.
how about the use of has been. the nurse notes that there has been no drainage since the client’s return..is ‘has been’ past tense or what?
I am having a hard time here..trying to comprehend if it’s on june 2005 or in june 2005….but this site helped me a great deal ! Realized it should be in june 2005 and it’s on june 23, 2005 or june 3 (with the absence of year, use ON only if the month and date is present)….Thanx a bunch! God bless
ADDITIONAL: There’s a rule of when to use ‘in/on’ when pertaining to what if vehicles are ‘public’ or not. But, I’m not sure if, if you are pertaining to a public vehicle, you would use ‘on’.
Can someone solve this question?
Thank you very much guys.
You are awesome . I am from Turkey , all that staff is so useful for people who learn English . I like English grammar ,but i confuse prepositions sometimes.

hi… i find this site very helpful. here’s mine..
do we say, “Your hair is in the air” or “Your hair is on the air” ?

i think my guess is incorrect since it sounds odd.
(
perhaps it’s “hair in the air”. i get really confused with these two prep.
Re the original post: You suggest “The ship is ON the sea” – seriously, or was that a typo? That sounds at least as weird as many of the other unidiomatic examples you are countering. In BrE, a ship is AT sea and if I’d heard “on the sea” in American literature or films, I’m sure I’d have remembered it.
@Annette: The “rule” about not ending a sentence with a preoposition never was a real rule in English. It was true in Latin and some people therefore applied it to English as well. Sometimes it is ugly and confusing to end with a preposition and sometimes it’s the best way to express something. It’s style, not grammar.
As a frequent observer of the space industry I get many confusing remarks from people in the USA, for example. They say “on orbit”, I say “in orbit”. Recently I saw an article from NASA titled An event was occurring “in July 7″. Some people in the USA say it my way, some say the other way. What is going ON here????
Is it correct to say “…this request for travel appears in the approved budget plan…” or “…this request for travel appears on the approved budget plan…”
@alex: To me, “budget plan” sounds provisional, but you say it’s “approved”, so I’d remove the redundancy and write either “in the approved budget” or “on the approved plan”.
Whatever, still confusing.

if IN means inside something.. why do we say “he was not on the train” instead of “he was not in the train” ?
@Herbert: Perhaps because it’s short for “on board”? (That’s just a guess.)

@Elissa: In British English, most people use “on”. However, I don’t think that is the case with AmE as I have heard many Americans omit it.
I am still confused in using “IN” as a past tense when referring to days or months and “ON” as future tense when referring to days and months or even year.
please reply.

Examples for in/on/at:

I think i get the explanation above, but please i need to check with you on this one. Do you put one “in copy” of a mail or you put them “on copy”?
I always thought the former was correct, but i started working at this new place and everyone, from the CEO down to the clerk say ” please put me ON COPY!! and it really gets on my nerves, but i realise that i need to find have a grammatical reason to back my assertion.
I don’t know what country you are in, Fenella, but I’ve never heard either phrase in England. Over here, we say, “send me a copy” or “CC me”. However, in your circumstances, I would do as the CEO does.
can you tell me which one is correct
influence of media in our lives
influence of media on our lives
I am writing the proposal, but I confuse how to use “in” or “on”
in the topic “A study of IT (in or on) Thai website)
How about this wee observation. The use of ‘in’ and ‘on’ CAN relate to size – You travel IN a car (small) but ON a train (large ), sail IN a boat (small ) but ON a ship (large), you holiday IN a country(large) but ON an island (small ). I suppose that this will serve to merely confuse people even further !
but what about weather?what do you use?is it in or on?
Is correct to say “Call from contact not registered on twitter”

I wish this website could help me in my upcoming exam.
Im helping my daughter on her assignments right now. But it comes to a point where I couldn’t identify which one is proper to use:

I actually told here that she can just use either of the two. But somehow, I feel one is more appropriate.
Can anybody enlighten me on this please?
Thanks.

Thanks a lot for this piece of very informative tip. It is very helpful.
Which one is correct, On the same day or In the same day?
I often confused with “for” vs “on”. For example, “leave on the occasion” or “Leave for the occasion”? “Algorithm for distributed computing” or “Algorithm on distributed computing”? Thank in advance.
I searched this page to only know that when I say month & day I use on. But if only month, use in. Thank you !!
