Etymology
The Online Etymology Dictionary states that ‘jynx’, meaning a charm or spell, was in usage in English as early as the 1690s.[3] The same source states that ‘jinx’, with that specific spelling, is first attested in American English in 1911. Jynx/jinx is traced to the 17th-century word jyng, meaning “a spell”, and ultimately to the Latin word iynx, also spelled jynx, as in Latin ‘j’ and ‘i’ are the same letter.[4] The Latin iynx came from the Greek name of the wryneck bird, iunx, associated with sorcery; not only was the bird used in the casting of spells and in divination, but the Ancient Romans and Greeks traced the bird’s mythological origins to a sorceress named Iynx, who was transformed into this bird to punish her for a spell cast on the god Zeus.
