Ancient Greek

Etymology

From Proto-Indo-European *-i-h₂, related to -ίᾱ (-íā) (from Proto-Indo-European *-i-eh₂). Cognate with Latin -ia. In some contexts, (e.g. in words like ἀλήθεια (alḗtheia) and πᾰρᾰ́νοιᾰ (paránoia)) the use of this suffix may have been an innovative replacement of earlier formations in -ίᾱ (-íā) (which was kept or changed to -ίη (-íē) in some dialects).

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). It also undergoes metathesis, resulting in -ιρᾰ (-ira), and -ινᾰ (-ina).
