knifepoint

the compound word knifepoint is a modern english formation that transparently combines two ancient roots to describe a specific and threatening situation. the first element, knife, descends from old english cnīf, a common germanic term for a bladed implement. the second element, point, traces back to latin pungere, meaning 'to prick or pierce', via old french. when combined, the literal meaning 'the sharp tip of a knife' evolved by metonymy to signify the situation of being threatened with that weapon, a concise and vivid example of how english creates precise terminology through compounding.

Structure: knife + point knife: from old english cnīf, of germanic origin; the core element denoting the cutting tool. point: from old french point, from latin punctum 'a small hole made by pricking', from pungere 'to prick'; the element denoting a sharp end or tip.
