-εῖος

Ancient Greek

Alternative forms

• -ήϊος (-ḗïos) – Ionic

Etymology

• Partially from a union of a stem vowel ε and -ιος (-ios), usually from stems in -εύς (-eús) (originally *-εϝ-, whence the Ionic diaeresis), and sometimes applied to other stems.
• Partially from -εῖϝος, from Proto-Indo-European *-iHwós, an extended form of *-wós. Note the double Latin adoption -īvus (e.g. Argīvus) and -ēus (e.g. mūsēum). Cognate with Latin -īvus.
