'unconventionally-shown' originates from the prefix 'un-' meaning 'not,' combined with 'conventionally,' derived from 'convention,' which comes from Latin 'conventio,' meaning 'a coming together.' 'Shown' is the past participle of 'show,' from Old English 'sceawian,' meaning 'to look at.'

'unconventionally' evolved from 'convention' with the prefix 'un-' added to indicate negation, while 'shown' is the past participle form of 'show,' which has remained consistent in its usage.

Initially, 'convention' referred to a formal assembly or agreement, but over time, it evolved to mean a standard or norm. 'Unconventionally-shown' now refers to something presented in a non-standard way.
