'purposely-shrunk' originates from the combination of 'purposely' and 'shrunk', where 'purposely' means 'intentionally' and 'shrunk' is the past participle of 'shrink', meaning 'to reduce in size'.

'purposely' comes from Middle English 'purposely', and 'shrunk' is the past participle of 'shrink', which comes from Old English 'scrincan'.

Initially, 'shrink' meant 'to contract or become smaller', and 'purposely' meant 'with intention'. Together, they convey the idea of intentional size reduction.
