Common mistakes

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

Using by instead of from for materials

From is preferred for the original source or substance.

Treating in as a fixed preposition

In usually adds context such as place or time.

Using at as the main complement

At normally introduces time or location, not the thing produced.
