Frisk Etymological English

Grammatical information: m.
Meaning: name of a heros and king of Athens, son of Ge, father of Pandion (A., E.); also name of a Trojan, son of Dardanos, father of Tros (Υ 219, 230).
Other forms: Cf. Ε᾽ρεχθευς (B 547 (sic!), η 80), which is also a surname of Poseidon (inscr.); on Attic vases ᾽Ερεχσες; also Ε᾽ριχθευς (Pape-Benseler 379); cf. Ε᾽ριχθώ a soothsayer in Thessaly. Note the soothsayer Εριχθώ in Thessalia (Luc. Phars., see also Ov. Her. 15, 139), which confirms (Pre-)Greek origin.
Derivatives: οἱ Ἐριχθονίδαι = Ἐρεχθεΐδαι (IG 3, 771; poet., Roman times).
Origin: PG [a word of Pre-Greek origin]
Etymology: Uncertain; the name will be very old, cf. the fact that he is called the son of the Earth; the name will be Pre-Greek. There is no explanation for the coexistence of the two names (after αὐτοχθονος?) cf. the name in -ων of Hermes; cf. Ερυσίχθων. Is the form with -χσ- an Atticism, or is it wider spread? Connection with ἐρέχθω is improbable.
