v
To enjoy yourself noisily and in a lively way, often in a group.
Etymology
The verb 'roister' entered English in the mid-16th century from the obsolete French verb 'ruister', which meant 'to be noisy, to brawl'. The French term itself likely originated from 'rustre', meaning 'ruffian' or 'boor', a word of Latin descent from 'rusticus' (rustic, rural). The core semantic thread connects the boorish, unruly behavior associated with a country lout to the modern sense of boisterous, loud, and rowdy merrymaking. Over time, the negative connotation of bullying or ruffian-like conduct softened, leaving the primary meaning of lively, noisy revelry.
Analysis
This word is a simplex loanword from French. It does not contain separable, productive morphemes in modern English.
