According to Beekes, from Pre-Greek. The traditional derivation from Proto-Indo-European *ser- (“to watch over, protect”)[1][2] (whence Latin servō (“to maintain, protect”)) has become far less tenable after the discovery of the cognate Mycenaean Greek (ti-ri-se-ro-e), whose initial ti- cannot be regularly derived from *ser-.[3] Compare perhaps Ἥρα (Hḗra).
ἥρως • (hḗrōs) m (genitive ἥρωος); third declension
Because the root of ἥρως (hḗrōs) ends with a vowel instead of a consonant, shortenings are common, such as ἥρως (hḗrōs) for the genitive singular and ἥρῳ (hḗrōi) for the dative singular.
