Somewhat uncertain, but appears to be from Proto-Indo-European *-tew- + *-r-eh₂. Note however that some cases are built on agentives in -tōr: e.g. cēnsūra, gladiātūra.[1] Resemblance to the future active participle -tūrus and archaic infinitive -tūrum is evidently accidental, though substantivizations like futūrus may have reinforced the use of -tūra.
Productive in earlier Latin but gradually overtaken by -tiō.
-tūra f (genitive -tūrae); first declension
The suffix -tūra is added to the supine form of a verb to create a first-declension noun naming the verb's action or the result of that action.
The suffix -tūra resembles the feminine form of (but may not be related to) the future active participle ending -tūrus, which describes impending or imminent action (e.g. pictūrus "about to paint"; scrīptūrus "on the point of writing").
First-declension noun.
