UK[ˈpɪnsə]US[ˈpɪnsər]

Etymology
The word 'pincer' entered English in the 14th century from the Old French word 'pincier', meaning 'to pinch'. This Old French term is thought to be of Gaulish origin, related to words for 'point' or 'peak', which conceptually connects to the pinching action. The tool was named for its function—to pinch or squeeze—and this name was later applied metaphorically to the similar gripping claws of crustaceans. The journey from a Celtic root implying a pointed action to the specific tool and anatomical feature illustrates a clear functional naming logic.
Analysis
The word 'pincer' is a simplex loanword from Old French. It is not productively formed from separable morphemes in modern English.
Examples
He used a pair of pincers to pull the nail out of the wood.
