Shades of meaning
That is empty which contains nothing; that is vacant which is without that which has filled or might be expected to fill it; vacant has extensive reference to rights or possibilities of occupancy. A vacant room may not be empty, and an empty house may not be vacant. Vacant, as derived from the Latin, is applied to things of some dignity; empty, from the Saxon, is preferred in speaking of slight, common, or homely matters, tho it may be applied with special force to the highest; we speak of empty space, a vacant lot, an empty dish, an empty sleeve, a vacant mind, an empty heart, an empty boast, a vacant office, a vacant or leisure hour. Void and devoid are rarely used in the literal sense, but for the most part confined to abstract relations, devoid being followed by of, and having with that addition the effect of a prepositional phrase; as, the article is devoid of sense; the contract is void for want of consideration. Waste, in this connection, applies to that which is made so by devastation or ruin, or gives an impression of desolation, especially as combined with vastness, probably from association of the words waste and vast: waste is applied also to uncultivated or unproductive land, if of considerable extent; we speak of a waste track or region, but not of a waste city lot. Vacuous refers to the condition of being empty or vacant, regarded as continuous or characteristic.
