'adminicle' originates from Latin, specifically the word 'adminiculum,' where 'ad-' meant 'to' and 'miniculum' meant 'support.'

'adminiculum' transformed into the French word 'adminicle,' and eventually became the modern English word 'adminicle' through Middle English.

Initially, it meant 'support or aid,' but over time it evolved into its current meaning of 'supporting document or evidence.'
