Etymology
The word 'cowpox' is a transparent compound formed in Modern English from two native Germanic elements. The first element, 'cow', derives from Old English 'cū', a term for the female of domestic cattle, tracing back to Proto-Germanic. The second element, 'pox', is a variant of 'pocks', the plural of 'pock', meaning a pustule or blister, which entered English from a Germanic root. The compound directly and logically names the disease by its host animal ('cow') and its primary symptom (the 'pox' or pustular rash). Its historical significance stems from Edward Jenner's late 18th-century observation that milkmaids who contracted cowpox were immune to smallpox, leading to the development of the first vaccine.
