常見錯誤

❌I am vastly happy to meet you.
✅I am extremely happy to meet you.
💡'vastly' sounds unnatural with personal emotion adjectives that do not imply comparison or measurable degree.
❌The meal was vastly good.
✅The meal was very good.
💡'vastly' is not a general intensifier; it works best when there is a sense of scale, difference, or measurable change.
