'unusually-moved' is a compound word formed from 'unusual' and 'moved'. 'Unusual' originates from the Latin word 'usualis', meaning 'customary', with the prefix 'un-' indicating 'not'. 'Moved' comes from the Latin 'movere', meaning 'to move'.

'Unusual' evolved from the Middle English 'unusual', while 'moved' transitioned from the Old French 'mover', eventually becoming the modern English 'moved'.

Initially, 'unusual' meant 'not common', and 'moved' meant 'to change position'. Over time, 'moved' also came to mean 'emotionally affected', leading to the modern meaning of 'unusually-moved'.
