silent: [16] Silent comes from the present participle of Latin silēre ‘be silent’. It is not clear what the origins of this were, although it seems likely to be related in some way to Gothic anasilan, a verb which denoted the wind dying down, and also perhaps to Latin dēsinere ‘stop’ (in which case its underlying meaning would be ‘stop speaking’). The Latin-derived noun silentium actually reached English much earlier than the adjective, as silence [13]. [silent etymology, silent origin, 英语词源]
