From Proto-Italic *natriks, from Proto-Indo-European *(s)nh₁-tr-ih₂-[1]. Cognate with German Natter, English adder. According to a proposal of André Martinet, the /ks/ in the nominative singular developed from word-final *h₂s, and /ik/ subsequently spread from the nominative singular to other forms of the word by paradigmatic leveling; Schrijver 1991 rejects this hypothesis, but Rasmussen 1993 considers it plausible.[2]
A pronunciation with a long vowel in the second syllable is attested by the time of Priscian (see Pronunciation below); this may have been caused by the much greater frequency of nouns ending in -īx, -īcis compared to those ending in -ĭx, -ĭcis, and more specifically by the possibility of reinterpreting the word as a feminine agent noun derived from the verb no, nāre (“swim”) and the suffix -trīx (“-tress”).
The fragment of Lucilius cited below (definition 2) requires both vowels to be short in order for the line to scan as a hexameter.[3] However, the 6th-century grammarian Priscian lists this word among deverbal nouns ending in -trīx with long ī, implying that by his time an analogically altered form with a long vowel in the second syllable was in use.[4]
