Grammar Rules Explanation

The confusion happens because English has three verb forms:

1. Base form → eat
2. Past simple → ate
3. Past participle → eaten

Why “Ate” is Correct Sometimes

“Ate” is a standalone past tense verb, meaning it does not need help.

Why “Eaten” is Correct in Other Cases

“Eaten” must be used with auxiliary verbs because it is a past participle, not a complete tense on its own.

📚 According to standard grammar rules referenced by Merriam-Webster, past participles are used in perfect tenses and passive voice constructions.
