'unusually-delivered' originates from the combination of 'unusual' and 'deliver', where 'unusual' means 'not usual' and 'deliver' means 'to bring or transport to the intended recipient'.

'unusual' changed from the Old French word 'usuel' and 'deliver' from the Old French 'delivrer', eventually becoming the modern English words 'unusual' and 'deliver'.

Initially, 'unusual' meant 'not common' and 'deliver' meant 'to set free', but over time, they evolved into their current meanings of 'not typical' and 'to transport to a recipient'.
