- 細かい - fine, minute (focuses on small parts)
- 詳細 - details (noun, more formal)
- 具体的 - concrete, specific (about the kind of information, not its amount)
- 大まか - rough, broad-brush: the opposite of sense 1
Usage
- Sense 2 takes に, never を: 歴史に詳しい. について works with verbs of knowing but not with this adjective.
- Calling someone 〜に詳しい is a compliment short of claiming 専門 (professional expertise), so it is safe to use about a hobby or side interest.
- 詳しくない is the standard modest disclaimer before giving an opinion — it softens rather than refuses.
