词源
late Middle English: from Latin deponent- 'laying aside， putting down' （in medieval Latin 'testifying'）， from the verb deponere, from de- 'down' + ponere 'place'. The use in grammar arose from the notion that the verb had 'laid aside' the passive sense (although in fact these verbs were originally reflexive).
