several: [15] Etymologically, several means ‘separate’. It comes via Anglo-Norman several from medieval Latin sēparālis, a derivative of Latin sēpar ‘separate’. This in turn was formed from sēparāre ‘separate’ (source of English separate), whose Vulgar Latin descendant *sēperāre passed into English via Anglo- Norman severer as sever [14]. Several’s original sense ‘separate, individual’ survives in legal terminology, but it has been superseded in the general language by ‘many’, which emerged in the 16th and 17th centuries via ‘different, various’.

By dreams, each one into a several world
