Problems with Prepositions

Prepositions are words that often show direction: below, above, over, under, around, through, in, out, between, among, to, toward(s). Other common prepositions include of, for (also sometimes a conjunction), from, with, like (also sometimes a verb).

Rule 1: You shouldn’t use unnecessary prepositions.

Incorrect: Where did he go to?


Correct: Where did he go?


To is unnecessary because the meaning is clear without it.

Incorrect: I don’t know where my jacket is at.

Correct: I don’t know where my jacket is.

Incorrect: Please get the cat off of the table.

Correct: Please get the cat off the table.

Rule 2. Many of us learned that it is always incorrect to end a sentence with a preposition. This is a myth! The rule actually states that it is incorrect to end a sentence with an unnecessary preposition. Sentences may end with necessary prepositions.

Correct: That is something I cannot agree with.

Even though you could rewrite the sentence so that with does not end the sentence (That is something with which I cannot agree.), it is not incorrect to end this sentence with a preposition because it is a necessary one.


Correct: How many of you can I count on?

On is a necessary preposition. Alternately, you could write the sentence this way:

On how many of you can I count? But doesn’t this tortured phrasing to avoid ending a sentence with a preposition seem absurd?
