Common mistakes

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

Using chew with instead of chew on

Use chew on for ideas or objects being bitten.

Confusing chew through and chew on

Chew through suggests complete penetration or consumption.

✕ The mouse chewed on the wire in two minutes. ✓ The mouse chewed through the wire in two minutes.

Treating chew by as a fixed pattern

By usually adds location or method information, not a selected preposition after chew.

Using chew at for deep consideration

Chew at is physical biting, not mental consideration.

✕ We need to chew at this idea. ✓ We need to chew on this idea.
