'robustly-crafted' originates from the combination of 'robustly' and 'crafted'. 'Robustly' comes from the Latin word 'robustus', meaning 'strong' or 'sturdy', and 'crafted' is derived from the Old English 'cræftan', meaning 'to make or build'.

'Robustly' evolved from the Latin 'robustus' through Middle English, while 'crafted' evolved from Old English 'cræftan'. Together, they form the modern English term 'robustly-crafted'.

Initially, 'robustly' meant 'strongly' and 'crafted' meant 'made'. Over time, the combination has come to mean 'skillfully and strongly made'.
