Commonly pairs with adjectives expressing difference or scale (different, superior, greater, larger) and verbs of change or measurement (improve, increase, underestimate, vary). Less frequent with neutral descriptive adjectives (e.g. 'vastly happy' sounds unnatural).

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.
