erus

• herus

From Proto-Italic *ezos (“master”), from Proto-Indo-European *h₁esh₂ós (“master”). Cognate with Hittite 𒅖𒄩𒀀𒀸 (“išhāš "master"”).

A connection with heres (“heir”) and hirudo (“leech”) has also been proposed by Charlton Lewis and Charles Short, making its stem instead from Proto-Indo-European *ǵʰeh₁ro- (“derelict”). Cognates would include Ancient Greek χήρα (khḗra, “widow”), Sanskrit हरति (harati, “to seize”) and हरण (haraṇa, “abduction”).
