常見錯誤

❌She defiantly wants to come to the party.
✅She definitely wants to come to the party.
💡'defiantly' means 'in a rebellious way,' not 'certainly.'
❌I am definitely not sure about the answer.
✅I am definitely sure about the answer.
💡'definitely' and 'not sure' contradict each other; use 'not sure' on its own or replace with 'completely'.
