A fire extinguisher (from French); also used historically to describe a device or person that extinguishes something.
From French 'extincteur,' derived from Latin 'extinctus' (extinguished). The French term was borrowed into English technical vocabulary in the 19th century but remains rare in modern English.
In French, fire extinguishers are still called 'extincteurs,' and this shows how the same root word took different paths in different languages—French kept the fancy version while English switched to the compound form!
