澡

Left radical 氵 is the three-drop side-form of 水 (water). It marks 澡 as a water-action: bathing, washing the body all over. The water radical groups 澡 with the entire family of liquid-related chars - 河 (river), 海 (sea), 洗 (wash), 浴 (bathe) - 澡 sitting close to 浴 in the bathing/cleansing sub-family.

Right phonetic 喿 supplies the sound - zào shifted to zǎo through tone change only. 喿 itself depicts three 口 mouths above a 木 tree, picturing birds chirping in the branches. As phonetic in 澡 it gives the same vowel and consonant; same series produces 燥 (zào, dry), 噪 (zào, noisy), 躁 (zào, restless) - all sharing the zào rime.
