Origin & History of “worm”

The ancestral meaning of worm appears to be ‘snake’; its application to smaller limbless creatures is a secondary development. It comes from a prehistoric Germanic *wurmiz, *wurmaz, which also produced German wurm, Dutch worm, and Danish orm ‘worm’ and Swedish orm ‘snake’. And this in turn went back to Indo-European *wrmi-, *wrmo- (source also of Latin vermis, from which English gets vermilion and vermin), a possible derivative of the base *wer- ‘turn, twist’ (source of English convert, reverse, etc) – in which case the worm would be etymologically the ‘twisting’ or ‘winding’ creature.
