#### Derived terms
## Latin
### Alternative forms

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

### Etymology

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. 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).

### Pronunciation

* (Classical Latin) IPA: /tor/, [t̪ɔr]
* (modern Italianate Ecclesiastical) IPA: /tor/, [t̪or]

### Suffix

-tor m (genitive -tōris); third declension
* -er; used to form a masculine agent noun

#### Usage notes

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”)
