The word "subtle" originates from Latin subtilis, combining sub- ("under") and -tilis (from texere, "to weave"). It originally described something finely woven or thin, later evolving metaphorically to mean "delicate" or "hard to detect." The spelling shifted in Old French (soutil) before entering Middle English as sotil, eventually standardizing to "subtle." The modern sense reflects both physical fineness and intellectual nuance.
