From Latin vermiculatio, from vermiculārī[1] + -tiō (“suffix forming nouns relating to actions または the results of actions”) (ultimately from Proto-Indo-European *-tis (“suffix forming abstract または action nouns from verb roots”)). Vermiculārī is the present active infinitive of vermiculor (“to be worm-eaten, wormy”), from vermis (“worm”) (from Proto-Indo-European *wr̥mis (“worm”), possibly from *wer- (“to turn”)).
