Synonyms: empty, vacant, blank, void, vacuous
These adjectives mean without contents that could or should be present. Empty is the broadest and can apply to what lacks contents (an empty box), occupants (an empty seat), or substance (an empty promise). Vacant has a similar range of application, including lacking an occupant (a vacant auditorium), an incumbent (a vacant position), or something useful or substantial (a vacant lot); it can also refer to what is without intelligence or expression (a vacant stare). Blank applies specifically to the absence of writing or images on a surface (a blank page; a blank screen) and can extend to a lack of awareness or understanding (a blank look). Void emphasizes the utter degree to which something is lacking, whether physical (a planet void of life) or intangible (a humdrum performance void of spirit or energy). Vacuous describes what is lacking in substance, interest, or intelligence (vacuous entertainment; a vacuous personality). See Also Synonyms at vain.
