to show
📊 演 perform + 示 show = to demonstrate, give a presentation
演 carries the sense of performing or acting out; 示 means to show or reveal. Together: acting something out so others can see how it works — a demo or presentation.
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.
示 — altar 示 (二 + 小); originally 丅 with three strokes
示 is a pictograph of an ancient altar or sacrificial stand, with the top line representing heaven and the strokes below depicting offerings or hanging banners. It originally meant 'to show' something to the spirits, and by extension came to mean 'to show, display, or indicate' in general. As a radical, it appears in many characters related to ritual, worship, and divine matters.
