'luckily-set' is a compound word formed from 'luckily' and 'set'. 'Luckily' originates from 'luck', which comes from Middle Dutch 'luc', meaning 'happiness or good fortune'. 'Set' comes from Old English 'settan', meaning 'to place or put'.

'luckily' evolved from the Middle English 'luckely', and 'set' from the Old English 'settan'. Together, they form the modern English compound 'luckily-set'.

Initially, 'luckily' meant 'by good fortune', and 'set' meant 'to place'. Together, they convey the idea of being placed in a fortunate position.
