Etymology

Etymology 1

Reanalysed from -ation, -tion, from Middle French -tion, -cion, from Latin -tiō. By surface analysis, this suffix is added to verbs derived from Latin perfect participle stems.

Etymology 2

Possibly reanalysed from inion, which is of Ancient Greek origin. In many cases also analysable as the neuter form of an Ancient Greek adjective in -ιος (-ios).

Etymology 3

From Ancient Greek ἀπόγειον (apógeion, “apogee”), containing -ιον (-ion). Compare also -ium.
