also: さりゃく
noun
Archaic term for a plan, tactic, or strategy. Not used in modern Japanese; encountered only in historical or classical texts.
古い軍記物には「作略」という言葉が戦術の意味で出てくることがある。
In old war tales, the word 作略 sometimes appears meaning a tactic or strategy.
The exact derivation is uncertain; the kanji 作 (make) and 略 (abbreviation/strategy) suggest a constructed plan or stratagem. The reading さくりゃく is a sound change from さくりゃく.
