launderette

the word 'launderette' is a mid-20th century british coinage, a blend of 'launder' and the french diminutive suffix '-ette'. the root 'launder' traces back to the latin verb 'lavare', meaning 'to wash', which is also the source for words like 'lavatory' and 'lava'. the suffix '-ette' was borrowed from french, where it commonly indicates a smaller or more informal version of something, as seen in 'kitchenette' or 'cigarette'. therefore, the term literally constructs the concept of 'a small-scale place for laundering', efficiently describing a self-service shop housing compact, coin-operated washing machines for public use.

Structure: launder (to wash clothes) + ette (diminutive suffix) launder (from middle english 'lavendre', from old french 'lavandiere', ultimately from latin 'lavare' meaning 'to wash'); ette (a diminutive suffix of french origin, used to form nouns denoting a small or compact version of something).
