From Proto-Balto-Slavic *wandō (genitive singular *undnes); compare Latvian ûdens, Old Prussian wundan, Proto-Slavic *vodà. Ultimately from Proto-Indo-European *wódr̥. The nasal infix is parallelled in Latin unda (“wave”), presumably analogically brought into the nominative from the oblique stem (cf. Proto-Indo-European genitive singular *udnés). The paradigm would then subsequently have been put back in line with other en-stem nouns (e.g. akmuõ).[1]
Clusters of the shape *nCn apparently blocked the action of Winter's law; compare also ugnìs.
