What does dewormed mean?
Dewormed describes an animal that has received treatment to remove intestinal worms or other internal parasites. It is formed from the verb 'deworm' and is especially common in veterinary, pet-care, and livestock contexts, where responsible parasite control is important. The adjective may refer to a specific completed treatment, as in 'the puppies were dewormed,' or to an animal's status, as in 'a dewormed dog.' It does not necessarily mean that the animal will remain free of parasites; reinfection is possible, so repeated treatment may be needed according to veterinary advice. The word is useful because it concisely identifies both the action and its result: an animal has not merely been examined or treated in general, but has specifically been treated against worms. It is a natural everyday word rather than a highly technical term.

Where does dewormed come from?
Dewormed is an English participial adjective formed from 'deworm,' a compound of 'de-' and 'worm,' with the past-participle ending '-ed.' 'Worm' descends from Old English 'wyrm' and is related to Latin 'vermis,' the source of words such as 'vermin' and 'vermicular.' The result is a transparent word whose meaning follows directly from the older Germanic and Latin root associated with worms.
