Origin: IE [Indo-European] [117] * bʰidʰ- `convince, trust'

Etymology: With πείθω agrees formally exactly the Lat. themat. root-present fīdō, - ere, IE * bheidh-ō; semant. agrees however the Lat. verb with middle πείθομαι (cf. confīsus sum). Formal identity we find also with the Germ. verb for `wait' in Goth. beidan, OHG bītan etc.; the semantic cleft ('wait (for)' from `trust' or `conform, restrain' ?) is however not yet bridged. The causative too Goth. baidjan `compel', OHG beitten etc. `urge, demand' is semantically divergent; after Specht KZ 66, 205 ff. an agreeing. Gr. *ποιθέω (to which the reduplicated aor. πεπιθεῖν) would have been replaced by act. πείθω. -- The Greek system including the nominal forms is quite explainable from itself; the various adduced nouns, esp. from Lat., like fīdus (formally = the innovated πειθός), fĭdēs, foedus (not to εὑ-πειθής or to πεῖσα), to which perh. also Alb. bē f. `oath' and OCS běda `need' (IE * bhoidhā), do not help understand the Greek forms. Quite doubtful is the connection of πιστός with Alb. besë f. `belief, treaty, faithfulness', appar. from * bhidh-tā f. (= *πιστη; Hamp KZ 77, 252f.); besë rather innovation (Jokl in W.-Hofmann). -- Further forms w. rich lit. in WP. 2, 139f., 185, Pok. 117, W.-Hofmann s. fīdō.
