How to say "frivolous" in Japanese
Choosing the right word
- 軽薄けいはくna-adjective, nounThe most direct equivalent for a frivolous person, remark, or manner: flippant, superficial, and lacking seriousness or depth. Think of someone who jokes around when the situation calls for a serious attitude.
- 上っ調子うわっちょうしna-adjective, nounCovers 'frivolous' as surface high spirits: a flippant, buoyant manner in which someone stays cheerful and jokey instead of settling into seriousness. The lightness is on the surface, in the mood of the moment.
- 徒あだna-adjective, nounIts core senses are vain, futile, and transient, with 'frivolous' only secondary. For everyday frivolous behavior or speech it is seldom the word you want; choose it mainly when emptiness or transience is the point.
- 軽々しいかるがるしいi-adjectiveReally means rash, thoughtless, or imprudent; it fits 'frivolous' when that amounts to treating something serious too lightly, as in careless words or hasty actions. Not for someone who is merely lighthearted.
- 上滑りうわすべりno-adjective, na-adjectiveDescribes frivolous, careless talk or conduct that slides along the surface instead of engaging the matter at hand. A discussion that stays light and thoughtless, never sinking in, is typical.
Use 軽薄 for a flippant, shallow person or manner, 「上っ調子」 for surface cheerfulness, 「上滑り」 for talk that stays superficial, 「軽々しい」 for rash thoughtlessness, and 徒 hardly at all, since it chiefly means vain or transient.
