swimming pool
🏊 游泳池 = swim + swim + pool
游 means swim/wander, 泳 also means swim (the water radical 氵 makes it explicitly aquatic), and 池 means pool or pond. Together: the pool you swim in.
游 — water radical 氵 + 斿 (banner/streamer)
游 combines the water radical 氵 with 斿, which depicts a banner streaming in the wind. The original sense was a flag fluttering or floating, extended to drifting on water, swimming, and wandering. Today it commonly means to swim, travel, or roam.
