na-adjective, noun
Describes something done without care or refinement, often implying a lack of politeness or thoroughness. Used for attitudes, treatment, or work quality.
彼の対応はあまりにも粗略だった。
His response was far too crude.
粗略な仕事では顧客の信頼を失う。
You'll lose customers' trust with rough work.
The kanji 粗 means 'coarse' or 'rough', and 略 means 'abbreviation' or 'omission'. Together they suggest a lack of refinement or thoroughness. The reading そりゃく is the on'yomi of both characters.
