用法筆記

Only used with abstract nouns (concept, term, word, idea, notion, phrase). Never used for concrete objects or people in this sense. Distinguish from sense 1 (physical surfaces) and sense 2 (untrustworthy people) — if the subject is an abstract idea that resists clear definition, use this sense.
