Etymology Origin:
The word traces back to Latin vermis (worm), reflecting early associations with parasitic or destructive creatures. Over time, it expanded to include rodents and insects, then metaphorically to undesirable humans. The suffix -in (via Old French vermine) generalizes the term for collective harm.
