Etymology
The term 'hookworm' is a transparent Modern English compound, formed in the 19th century as parasitology developed. The first element, 'hook', directly describes the distinctive curved buccal capsule (mouthpart) the worm uses to attach to the host's intestinal lining. The second element, 'worm', is a generic term for an elongated, limbless invertebrate. The compound's logic is purely descriptive, naming the parasite for its most visually identifiable anatomical feature, making the term immediately comprehensible even to non-specialists upon its introduction.
