The origin of the word, 'cinema.'
In Ancient Greek, the verb, κινεῶ or 'kineȭ;' κινῶ or 'kinȭ,' means 'I move.' From the above Ancient-Greek verb, we derive the term, 'kinetic energy,' which - in Physics - is 'the energy that an object possesses by virtue of its being in motion .' We also derive the English noun, 'cinema,' from 'kinȭ.' In Ancient Greek, the noun, τὸ κίνημα or 'tò kínēma,' means 'movement.' A cinema is a device whereby we may watch feature-length films, or 'motion pictures.' In a 'motion picture,' the pictures are said * to move * , hence we also term them 'movies.'
