-tor

• -toru
• -ãtor
• -ãtoru

From Vulgar Latin -torius, -torium, and feminine -toari, toare from Vulgar Latin -toria, -toriam, both from Latin -tor. Ultimately from Proto-Italic *-tōr, from Proto-Indo-European *-tōr < *-tor-s.

1. -er (used to form nouns from verbs)

-tor (v-v^?, additive^?, VTV → VsV^?)

1. [verb]s bit by bit, continuously

• -sor (in forms derived from primarily third conjugation verbs with stems ending in -t-, -d-, -rg-, -ll-, or -rr-.)

From Proto-Italic *-tōr, from Proto-Indo-European *-tōr < *-tor-s. The -ō- from the nominative singular form was extended to all other forms by analogy; then word-final -ōr was shortened to -or by regular Latin sound laws, producing the Classical Latin paradigm with short -o- in the nominative singular and long -ō- elsewhere.^[1] Cognate to Sanskrit -तृ (-tṛ) (nominative singular -ता m sg (-tā)) and Ancient Greek -τωρ (-tōr), as well as -τήρ (-tḗr) from a separate ablaut *-tḗr. Compare Latin -trum (instrumental suffix), from Proto-Indo-European *-tr-o-m (instrumental suffix).

-tor m (genitive -tōris); third declension

1. -er; used to form a masculine agent noun

The suffix -tor is added to the fourth principal part of a verb to create a third-declension masculine form of an agent noun.

Examples:

cantor (“male singer”); masculine counterpart of cantrīx (“female singer”), from canō (“I sing”)

tōnsor (“male hair cutter”); masculine counterpart of tōnstrīx (“female hair cutter”), from tondeō (“I shear, shave”)

quadrātor (“stonecutter”), from quadrō (“I make square”)

The suffix -tor occasionally is added to a noun to create an agent noun, often in the extended form -ātor, as if from a first-conjugation verb.

Examples:

gladiātor (“gladiator”), from gladius (“sword”)

malleātor (“hammerer”), from malleus (“hammer”)

Third-declension noun.
