'quickly-sliced' originates from the combination of 'quickly' and 'sliced', where 'quickly' is derived from 'quick', meaning 'fast', and 'sliced' is the past participle of 'slice', meaning 'to cut'.

'quickly' evolved from the Old English word 'cwic', meaning 'alive', and 'sliced' from the Old French 'esclicier', meaning 'to split'.

Initially, 'quickly' meant 'alive', but over time it evolved to mean 'with speed', and 'sliced' has retained its meaning of 'cut'.
