noun
Refers to a careless mistake or failure to notice something important. Often used in negative expressions like 抜かりなく (without oversight) or 抜かりはない (there is no oversight).
準備に抜かりはない。
There is no oversight in the preparations.
抜かりなく手配を進めてください。
Please proceed with the arrangements without any slip-ups.
ミス is a general loanword for 'mistake', while 抜かり specifically implies a careless oversight or failure to attend to details.
手落ち also means 'oversight' or 'omission', but 抜かり often carries a nuance of being caught off guard or lacking thoroughness.
Derived from the verb 抜かる (ぬかる, 'to make a blunder' or 'to be careless'), which itself comes from 抜く (ぬく, 'to pull out' or 'to omit') with the sense of 'missing something'.
