noun, na-adjective
sloppiness; carelessness; oversight
Archaic noun/adjectival noun. In modern Japanese, this word is almost never used independently; it survives only in the negative expression 如才ない (じょさいない), meaning 'shrewd', 'sharp', or 'not careless'. The standalone form is obsolete.

「如才」という語は、現代では「如才ない」という形でしか使われない。
The word 如才 is used only in the form 如才ない in modern Japanese.
In old texts, 如才 can sometimes mean carelessness or oversight on its own.
The modern negative form meaning 'shrewd' or 'sharp'; the standalone 如才 is archaic and rarely used.
The exact derivation is uncertain. The kanji 如 (like, as if) and 才 (talent, ability) may have been used phonetically or semantically, but the word is now fossilized in the negative form 如才ない.
