English Grammar 101: Prepositions

Prepositions are used to link nouns and pronouns to other words within a sentence. The words linked to are called objects.

Usually prepositions show a spatial or temporal relationship between the noun and the object, like in the example below:

The cat is under the table.

Cat is the noun. Under is the preposition. Table is the object.

Here is a list with the most common prepositions: about, above, after, among, around, along, at, before, behind, beneath, beside, between, by, down, from, in, into, like, near, of, off, on, out, over, through, to, up, upon, under, and with.

Notice that you can also have a prepositional phrase, which is formed by the preposition and its object. A preposition phrase can function as adverb, adjective or noun. For example:

The dog was running under the rain.

The prepositional phrase “under the rain” acts as an adverb, specifying where the dog was running.

    Hmm. Prepositions were going to be my next “Mangled Monday” topic . . . I guess maybe I’ll wait a few weeks now! (grin)

    Notice that in the examples, each preposition has an object. For example, in the sentence “He ran under the car” “under” is the preposition, and “car” is the object of that preposition. When correctly used, prepositions have objects, which is why we don’t end sentences with prepositions. If the preposition is the last word in the sentence, it can’t be followed by the object it needs.

    Since this is a very common issue, we added it to our training manual, which we use in-house with our editors.

    When do you use “on” or “in” in front of a date? i.e…
    He was found on/in January 23, 2008
    or
    His next payment is due on/in March 2008?

    I had difficulty teaching sixth graders exactly what a preposition was about 30 years ago. The book definition, that a preposition shows the relationship between two nouns, just didn’t work for the children. A friend suggested, “A preposition can go anywhere a squirrel can.” That worked.

    Hey! I don’t known when to use “effort of” and “effort by”. Is there usage something to do we a group or an individual; an authorized body or an authorized individual?

    I would like know the correct form of at or in when refering to a place. For example: ….makes the social activity at the interior space more visible.
    or
    ….makes the social activity in the interior space more visible.

    What is the correct one and why?
    Is there a general rule for using prepositions?

    I really don’t know when to use the words above or on, especially when i want to talk about event happen at a particular time. may i say such as The pen is above the table or the pen is on the table which one is suitable to use between these two words?

    R Suresh:

    Good question. We frequently encounter this confusion when we work on documents by non-native speakers.

    If the event happens at a particular time, use ON. Ex: He received his gift on November 13, 2008.

    If the event happened during a time range, use IN. Ex: He received his gift in November, 2008.

    Regarding your pen (a red pen, I hope): In most cases, the pen will be ON the table. However, if it is on a shelf or is in some way placed on something else that is above the table, the pen is above the table. Two examples may help clarify.

    1. The plate is on the table.
    2. The plate is on a shelf, and the shelf is above the table, so the plate is also above the table.

    Veronica:

    Think about what is happening in your examples. You are describing something (social activity) that occurs WITHIN a confined space, so IN is more appropriate. This is like R. Suresh’s question about dates.

    Something happens IN (inside, within) an area, but it happens AT a specific place. This is similar to R. Suresh’s question.

    I work IN a building. I work AT 1500 Weston Street.
    I sleep IN the bedroom. I sleep ON the bed.
    I was born IN March. I was born ON March 5.
    The battle occurred IN Belgium. The battle occurred AT Waterloo.
    [Yes, I know. The battle actually occurred NEAR Waterloo.]
