🎭 演技 = 演 perform + 技 skill = an actor's performing skill

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.
