用法筆記

Merriam-Webster lists 'eaten' as a rare noun meaning 'something to eat : food', but this use is extremely uncommon in modern English. Learners should use 'food' instead. Example: 'We packed enough food (not 'eaten') for the trip.'

❌I have eat breakfast.
✅I have eaten breakfast.
💡After 'have' or 'has', always use the past participle form 'eaten', not the base form 'eat'.

用法筆記

The compound forms 'half-eaten' and 'uneaten' are far more common than bare 'eaten' used as an adjective. Native speakers rarely say 'an eaten apple'; instead they say 'a half-eaten apple' or 'an apple that has been eaten'.

常見錯誤

❌I threw away an eaten apple.
✅I threw away a half-eaten apple.
💡When used adjectivally, 'eaten' almost always needs a modifier such as 'half-' or 'un-', or a supporting clause.
