'agreeably-formed' originates from the combination of 'agreeably' and 'formed', where 'agreeably' is derived from 'agree' meaning 'to be in harmony' and 'formed' from 'form' meaning 'shape or structure'.

'agreeably' evolved from the Old French word 'agreer', and 'formed' from the Latin 'formare', eventually becoming the modern English word 'agreeably-formed'.

Initially, 'agreeably' meant 'in a manner that is pleasing', and 'formed' meant 'shaped'. Together, they evolved to describe something that is pleasingly shaped.
