🪖🎯 演 perform + 习 practice = a performed practice, i.e. a drill or maneuver
演 carries the sense of acting out or performing, and 习 means to practice or drill. Together they name a rehearsed run-through, like a military maneuver or fire drill done for training rather than the real event.
演 — water 氵 + 寅 (yín, phonetic)
演 is a semantic-phonetic compound: the water radical 氵 gives the meaning, originally referring to water flowing far and spreading out, while 寅 supplies the sound. From 'water extending' it broadened to 'develop, elaborate, perform,' as in unfolding a story or acting out a play.
