Explanation
Time, aspect, number, and agreement come from Chinese semantic units and context. They do not mutate the stored English-facing token identity.
Correct Examples
- He eat rice, not He eats rice
- Yesterday I buy phone, not Yesterday I bought phone
- She like phone, not She likes phones
Incorrect or Boundary Example
Natural English may use eats, bought, or likes, but those forms belong only in the Natural English field.
