Pronunciation[edit]

Suffix[edit]

-tiō f ‎(genitive -tiōnis); third declension

  1. -tion, -ation, -ing; used to form a noun relating to some action.

Usage notes[edit]

The suffix -tiō is added to the supine form of a verb to create a third-declension noun naming the verb's action or the result of that action.

Examples:
dictātiō ‎(a dictating, dictation), from dictātum, supine of dictō ‎(I dictate)
quadripartītiō ‎(a division into four parts), from quadripartītum, supine of quadripartiō ‎(I divide in four parts)

The suffix is occasionally added to other parts of speech, or appears in situations where no related verb apparently exists.

gradātiō ‎(making of a staircase or steps), from gradus ‎(step, pace).
mentiō ‎(a mention), from mēns ‎(mind, disposition)

Inflection[edit]
