The Chinese word 泳衣 (yǒngyī), meaning "swimsuit", is a straightforward compound noun formed by combining the character 泳 (yǒng), which means "to swim", with the character 衣 (yī), which means "clothing" or "garment". This follows a common grammatical structure in Mandarin known as a modifier-head construction, where the first character 泳 modifies and specifies the type of the second character 衣. Literally, it translates to "swim-clothing", logically and efficiently describing the item's purpose through the direct combination of two meaningful semantic components.
