coruscate + with + abstract noun

用法筆記

Almost always paired with 'with' followed by an abstract noun (wit, humour, brilliance, energy, technique). The subject is typically a person, a performance, or a creative work. Do not use for plain competence — the sense requires a lively, showy quality.

常見錯誤

❌The report coruscated with data.' (data alone is not a lively quality).
✅Her presentation coruscated with sharp wit and original ideas.
💡the quality after 'with' must be something vivid or brilliant.
