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. The relationship to the future active participle ending -tūrus, also of uncertain origin, is disputed: Miller 2006 considers the ending of the participle to descend from a lost infinitive *esom, whereas Fortson 2007 rejects that hypothesis and derives the participle ending from *-rós. In any case, substantivizations like futūrus may have reinforced the use of -tūra.
-tūra f (genitive -tūrae); first declension
Productive in earlier Latin, but gradually overtaken by -tiō.
This suffix is one of many (including -tus, -tor, -tiō, -tim, -tō, -tūra) that all use the same verb stem as the supine, perfect passive participle, and/or future active participle, found in the verb's fourth principal part. This stem is conventionally considered to end in -t- (or for some verbs, -s-), which would imply analyzing the suffixes as -us, -or, -io, -im, etc. However, from an etymological perspective it is more accurate to identify -t-/-s- as the initial consonant of these suffixes.
