'unconventionally-shaped' originates from the prefix 'un-' meaning 'not', the root 'convention' from Latin 'conventio' meaning 'agreement', and the suffix '-ally' indicating 'in a manner'.

'Convention' transformed from the Latin 'conventio' to the Old French 'convention', and eventually became the modern English word 'convention'.

Initially, 'convention' meant 'a coming together', but over time it evolved to mean 'a standard or norm', and 'unconventionally-shaped' now refers to something not adhering to these norms.
