carouse

the word 'carouse' entered english in the mid-16th century from the german phrase 'gar aus trinken', meaning 'to drink fully out' or 'to drain the cup'. this was a drinking toast. the phrase was adopted into french as 'carous' before entering english. the core logic of the word has always been associated with the act of hearty, communal drinking. its modern meaning expanded from the specific act of toasting to encompass the broader, noisy celebration and revelry that accompanies such drinking bouts, capturing the spirit of boisterous festivity.

this word is a loanword from german, adopted as a whole unit into english. it does not neatly segment into smaller, meaningful morphemes using its current english spelling.
