hamstring (English)

Where does "hamstring" come from?

The English word 'hamstring' is a compound noun formed by combining 'ham' and 'string'[1]. The first component, 'ham', descends from Middle English 'hamme' and Old English 'hamm', which traces back to Proto-Germanic 'hammō' and ultimately Proto-Indo-European 'kónh₂m' meaning 'leg'[3][5][6][11]. The second component, 'string', comes from Middle English 'streng' and Old English 'strenġ', ultimately originating from the Proto-Indo-European root 'strengʰ-' which refers to a 'rope', 'cord', or the act of tightening[2][4][7]. While the root of 'ham' remains uncertain, it is potentially connected to earlier reconstructions like 'hanmō'[11]. The term 'string' in Middle English likely incorporated influences from Old Norse 'strengr' to account for its modern phonetic form[19].
