From Proto-Italic *-trīks, from Proto-Indo-European *-trih₂, from *-tḗr. Cognate with the Sanskrit suffix -त्री (-trī) as in जनित्री (janitrī, “mother”); compare genetrīx. Equivalent to -tor + -ix.
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 using the following rules: replace -tus/-tum with -trīx, replace -sus/-sum or -ssus/-ssum with -strīx. Examples:
However, some show other differences in the stem:
