Frisk Etymological English

Grammatical information: prefix
Meaning: very, high (Il.),
Dialectal forms: Perh. in Myc. eri- /eri-/.
Compounds: esp. in Bahuvrihi's like ἐρί-(γ)δουπος, -σθενής, -τιμος, -αύχην; also ἐρι-βρεμέτης, -δμᾶτος (A. Ag. 1461 [lyr.]) a. o.; cf. Chantraine REGr. 49, 406.
Origin: XX [etym. unknown]
Etymology: Beside ἐρι- stands with the same meaning ἀρι-, which however like Skt. ari-, as opposed to ἐρι-, belongs in verbal adjectives, cf. s. v. and Schwyzer 434. One might think of a connection with ὄρνυμι rise etc. (ἐρι- beside *ἔρος?, cf. s. ἐρέας). - The comment in DELG is unclear to me.

Middle Liddell

insepar. prefix, like ἀρι-, to strengthen the sense of a word, very, much.
