From Proto-Italic *feiðō, from Proto-Indo-European *bʰéydʰeti (“to trust”), from the root *bʰeydʰ-. The perfect participle fīsus has been connected to Ancient Greek πιστός (pistós), hinting at a derivation from Proto-Indo-European *bʰidʰtós, itself a *-tós adjective to the root *bʰeydʰ-. However, according to the linguist Ville Leppänen, Lachmann's law cannot account for the vowel-length of the Latin term, perhaps indicating that a generalized e-grade was later introduced into the pre-form. Cognate to fidēs (“faith”) and Proto-Germanic *bīdaną.
