point of special interest
🔥📍 热 hot + 点 dot/point = a hot point, a hotspot
The character 热 means hot or heat, and 点 means dot, point, or spot. Together they literally form hot-spot — used for WiFi hotspots, trending topics, or any point of intense interest.
热 — 执 zhí (phonetic) + 灬 fire radical
热 is a semantic-phonetic compound: the bottom 灬 (a variant of 火 'fire') gives the meaning of heat, while 执 on top supplies the sound. Originally written 熱, it depicted fire below a phonetic element, and the meaning naturally extended from physical heat to 'hot' weather and 'enthusiastic' feelings.
点 — fire radical 灬 + 占 (zhān, phonetic)
Originally written 點, a semantic-phonetic compound: 黑 (black) gave the meaning 'small black mark or dot' while 占 supplied the sound. It first referred to ink spots, then extended to 'point, drop, a little,' and verbs like 'to mark' or 'to light (a fire),' reflected in the simplified form's 灬 (fire) component.
