Ancient GreekEdit


Like -ίᾱ (-íā), from Proto-Indo-European *-i-h₂. Cognate with Latin -ia.

After a consonant, the vowel *i changed to a semivowel *y and triggered palatalization in Proto-Greek, resulting in many nouns and adjectives ending in -σσᾰ (-ssa), -ττᾰ (-tta), -ζᾰ (-za), -ιρᾰ (-ira), and -ινᾰ (-ina).




-ῐᾰ (-iaf (genitive -ῐ́ᾱς); first declension

  1. Primitive suffix added to the stems of adjectives in -ύς (-ús) and some nouns to form feminine gender
    ἡδῠ́ς (hēdús, sweet, masculine) + ‎-ῐᾰ (-ia) → ‎ἡδεῖᾰ (hēdeîa, feminine)
    ἱερεύς (hiereús, priest, masculine) + ‎-ῐᾰ (-ia) → ‎ἱέρειᾰ (hiéreia, feminine)
  2. Suffix added to the stems of adjectives in -ής (-ḗs) to form abstract nouns
    ᾰ̓ληθής (alēthḗs, true) + ‎-ῐᾰ (-ia) → ‎ᾰ̓λήθειᾰ (alḗtheia, truth)

Usage notesEdit

Nouns formed with the suffix always have recessive accent.
