Prepositions with nouns

"With friend" or "of friend"?

"With friend" is possible in limited contexts, but English usually needs an article or possessive. "Of friend" is generally not idiomatic on its own.

Quick answer

Using prepositions with "friend"

English normally says "with a friend," "with friends," or "a friend of mine." The phrase "of friend" is not standard by itself. "With" expresses company, while "of" usually appears in possessive structures such as "friend of my brother."

She went to the concert with a friend.
He is a friend of mine from university.
They travelled with friends during the summer.

Common mistakes

Some combinations appear in real text but do not mean what learners often assume.

Leaving out the article after "with"

Singular countable nouns usually need an article or determiner.

✕ I went with friend. ✓ I went with a friend.

Using "of friend" alone

Use "friend of" with a noun or possessive.

✕ She is of friend. ✓ She is a friend of mine.

Confusing "friend" and "friends"

The plural form is needed for general groups.

Using "friend with" instead of "friends with"

The common expression is "be friends with."

✕ I am friend with her. ✓ I am friends with her.
