闲散 describes a state of being free, idle, or unoccupied — it can refer to a person who has no pressing work or obligations (free and at leisure), or to things that are unused or lying around (闲散资金 'idle funds', 闲散土地 'unused land'). As a stative verb (s.v.), it functions like an adjective in Chinese: you can say 他很闲散 ('he's very idle'). The tone is neutral to slightly negative when describing a person (implying laziness or lack of purpose), but neutral or practical when describing resources.
