'pimple-like' originates from the word 'pimple', which comes from Middle English 'pymple', meaning a small swelling or protuberance.

'pymple' transformed into the modern English word 'pimple', and the suffix '-like' was added to form 'pimple-like'.

Initially, 'pimple' referred to a small swelling, and 'pimple-like' evolved to describe anything resembling a pimple.
