You’ll hear some of these in conversation and see them on blog sites, but when it comes to formal writing, beware of these “all” words and expressions.
all of – I ate all of the cookies. The “of” is unnecessary. Better: I ate all the cookies.
alright – As my English teachers pounded into my brain, there’s no such word as “alright.” There is the phrase all right. Is it all right if I search your house?
already – This word is an adverb. Too late! The cat has already eaten the canary.
all ready – This is a phrase. When you are all ready, I’ll get the car. We were all ready to go to the movies.
altogether – This word is an adverb meaning “entirely.” Your idea is altogether wrong-headed.
all together – This is a phrase. All together, now, sing! The family was all together for Thanksgiving.
alot – This is the bane of English teachers and, I suppose, editors. The expression is a lot, two words. I like you a lot. My children read a lot. There is a word allot, a verb meaning “to divide into lots.” When I plan my day, I allot four hours to meals and a minimum of six hours to writing.
