Etymology: < cocked adj.³ (compare sense 3a at that entry) + centre n.²The β. forms may show the development of an epenthetic vowel, or may (if the α. forms originally showed a disyllabic pronunciation of the first element) show assimilatory devoicing, in either case suggesting that the identity of the first element had become opaque.
