vacant的词源

英文词源

vacant: vacant: [13] Latin vacāre meant ‘be empty’. Its present participle vacāns has provided English with vacant, while its past participle lies behind English vacate [17] and vacation [14]. It also formed the basis of an adjective vacuus ‘empty’, from which English gets vacuous [17] and vacuum [16] (the term vacuum cleaner is first recorded in 1903, and the consequent verb vacuum in 1922). English avoid and void come from a variant of Latin vacāre.
=> vacate, vacuum
