The word 悠闲 is formed by combining the characters 悠 and 闲, where 悠 is composed of 攸 (meaning "distant" or "prolonged") and 心 (meaning "heart" or "mind"), conveying a calm, unhurried mental state, while 闲 is composed of 门 (meaning "gate") and 木 (meaning "wood"), originally referring to a wooden barrier and later evolving to signify "leisure" or "idleness", so together they denote a state of being both mentally and physically at ease.
