冲澡 is a separable verb (离合词) meaning 'to take a shower'. The verb 冲 separates from the object 澡 when you add measure words, aspect markers, or duration — for example, 冲了一个澡 ('took a shower'), 冲过澡 ('have showered'), or 冲完澡 ('finish showering'). The full pronunciation is chōng zǎo, but the headword's pinyin in the examples below reflects only the first syllable chōng as given in the source data.
