'angora' originates from Turkish, specifically the place name 'Ankara' (older European form 'Angora'), where the Greek root 'ankýra' meant 'anchor'.

'angora' changed from the European place-name form 'Angora' referring to the city and its famous long-haired breeds, and eventually became the modern English word 'angora' used for the animals and their fiber/fabrics.

Initially, it meant 'of/from Angora (Ankara),' but over time it evolved to refer to the long, soft hair/fiber from Angora rabbits and, by extension, the animals and garments made of it.
