the word 'torque' entered english in the early 19th century from french, which had taken it from latin. its latin source, 'torquēs', referred specifically to a twisted metal necklace or collar, a prestigious item worn by ancient celtic and persian nobility. this concrete object sense derives from the latin verb 'torquēre', meaning 'to twist'. the modern scientific and engineering sense of a rotational or twisting force is a semantic extension from this original, physical concept of a twisted object, abstracting the core idea of 'twisting' into a measurable physical principle.

the word is a simplex loanword. it is borrowed directly from latin 'torquēs/torquis' (a twisted collar, necklace), which is derived from the verb 'torquēre' (to twist). the verb 'torquēre' itself is traced back to the proto-indo-european root terkʷ- (to twist).
