🌊 water 氵+ 曼 (màn, to extend) = water extending everywhere: to flood, overflow, run free
漫 — water radical 氵 + 曼 màn (phonetic)
漫 is a phono-semantic compound: the water radical 氵 gives the meaning and 曼 supplies the sound. It originally described water overflowing or spreading without bounds, and from that came extended senses like 'free, unrestrained, aimless,' as in 漫步 'to stroll' or 浪漫 'romantic.'
