Sense: adjective/1

All four words can describe something that is not in use, but they differ in scope and tone. Empty is the broadest — a box, room, street, or parking lot can be empty, with no implication about whether the emptiness is normal or temporary. Vacant is more formal and is the preferred term for job positions, hotel rooms, and rental properties; a 'vacant house' suggests it is available for occupancy. Free is the most casual option and is commonly used for seats, schedules, and resources: 'Is this seat free?' sounds natural in conversation, whereas 'Is this seat unoccupied?' sounds overly formal. Idle carries a slightly negative or evaluative tone when applied to people, often suggesting wasted time or laziness; machines can be idle neutrally, but an 'idle employee' may imply they should be working. For a learner, free is safest for everyday speech about personal availability, empty works for physical spaces, and vacant is appropriate for formal or property-related writing.

Etymology

LatinFrenchEnglish

Formed in late Middle English from the prefix un- (meaning 'not') attached to 'occupied', which comes from Latin occupare meaning 'to take over, seize, or fill'. The sense of a person being free from tasks followed the original sense of a physical space being empty.
