Inherited from Proto-Italic *-trīks, from Proto-Indo-European *-trih₂, from *-tḗr + *-ih₂. Cognate with the Sanskrit suffix -त्री (-trī) as in जनित्री (janitrī, “mother”); compare genetrīx. By surface analysis, -tor + -īx.
The origin of the medial -c- is unknown. Compare Proto-Slavic *-ica with the same element, and also with secondary thematicization.
-trīx f (genitive -trīcis, masculine -tor); third declension
The suffix -trīx forms feminine agent nouns from verbs. Its masculine counterpart is -tor. Most feminine agent nouns use the same verb stem as the supine, perfect passive participle, or future active participle, and can be derived from the verb's fourth principal part by replacing -tus/-tum with -trīx:
However, some show other differences in the stem:
If the fourth principal part ends in -sus/-sum or -ssus/-ssum, the prevailing pattern is to replace these endings with -strīx:
Third-declension noun.
