Etymology. From √ku- 'crooked, bent' (Sanskrit ku-) + -sala (instrumental suffix creating agent nouns). The underlying metaphor treats crookedness as lack of straightness—hence defect—making ku-sala literally 'not-straight, well-ordered', evolved to mean skillful and morally sound. Sanskrit cognate kuśala shares the root; Indo-European *skel- 'bend, curve' (English skill via Old Norse) shows the same association of straightness with competence.
