Origin: IE [Indo-European] [774] * h₂eid-\/ h₂oid- `swell'

Etymology: Of the presentforms only οἰδέω will be old. Through enlargement arose the causat. οἰδάνω with intr. οἰδάνομαι (cf. on Οἰδίπους), in the same way οἰδίσκομαι, -ω (Schwyzer 700 a. 709 f.); οἰδαίνω will be analog. after κυμαίνω, ὀργαίνω u.a., perh. also to οἰδῆσαι after κερδῆσαι: κερδαίνω a. o.; to οἰδῆσαι the late and rare οἰδάω. In οἰδέω some see an iterativ-intensive formation; but an agreeing primary verb is not attested. -- A certain cognate is Arm. ayt-nu-m `swell' with the primaryn aor. ayte-ay and the noun ayt (i-stem) `cheek', IE * oidi- (poss. * aidi-; cf. below); the nu-present is an Arm. innovation. Germ. presents some isolated nouns, a.o. OHG eiz, NHG dial. Eis `abscess, ulcer', PGm. * aita-z, IE * oido-s (* aido-s?; cf. formally close οἶδος n.); with r-suffix e.g. OHG eittar n. ' Eitar', PGm. * aitra- n. (cf. on Οἰδίπους), also in waternames, e.g. Eiter-bach (Krahe Beitr. z. Namenforsch. 7, 105 ff.). Isolated also Lat. aemidus (prob. after the synon. tumi-dus), in the vowel deviating from οἰδέω (ablaut oi: ai?, which could be * h₂ei-\/ h₂oi-); the non-Greek. forms can further continue both IE oi and ai. -- The Slav. forms adduced are polyinterpretable: OCS jadъ `poison'; even more doubtful Russ. etc. jadró, PSl. *jędro `kernel, testicle etc.' (with nasal infix?). Also other nasalised forms wit zero grade have been connected, e.g. Skt. índu- m. `drop', Balt. rivernames like Indus, Indura; all of it rather doubtful and for Greek unimportant.
