1.
stopgap; temporary; makeshift
The original meaning: a temporary, palliative measure that does not address the root cause of a problem.
2.
cowardly; sneaky; underhanded
The widely used modern meaning: acting in a petty, cowardly, or underhanded way to avoid direct confrontation. This usage arose from the negative connotation of avoiding proper solutions.
姑息 is a famous case of semantic shift in Japanese: its original meaning ('temporary, stopgap') has been largely replaced in everyday use by a new meaning ('cowardly, sneaky').
Usage
- Functions as a な-adjective and as a noun.
- Originally from Chinese, where 姑 means 'for the time being' and 息 means 'to rest/breathe'; the literal sense is 'a momentary breather' — i.e., a stopgap.
- Surveys by the Agency for Cultural Affairs show over 70% of speakers now use it in the newer 'cowardly/sneaky' sense. Both meanings are now considered acceptable in modern Japanese, but the new sense dominates conversation.
- The original sense survives mainly in medical terminology.
- Modifier (姑息な + noun): 姑息な手段 (a sneaky/stopgap means), 姑息なまね (sneaky behavior), 姑息な言い訳 (a cowardly excuse)
- Predicate: そのやり方は姑息だ (that approach is underhanded)
- Medical (original sense): 姑息的治療 (palliative treatment)
