Etymology
The word 'rotatable' is a modern English formation built upon the established verb 'rotate'. The core morpheme 'rotat-' originates from the Latin verb 'rotare', meaning 'to turn in a circle', which itself is derived from 'rota', the Latin word for 'wheel'. This etymological link vividly connects the modern concept of turning on an axis to the ancient image of a wheel's circular motion. The suffix '-able', of Latin origin via Old French, is productively attached to verbs to create adjectives indicating a passive capacity or potential. Therefore, 'rotatable' logically constructs its meaning as 'capable of being turned', directly following the compositional pattern of its Latin-derived components.
