'torchbearer' originates from Modern English as a compound of 'torch' + 'bearer'. 'torch' itself comes from Old French 'torche', from Late Latin 'torca' (a twisted object used as a torch), and 'bearer' comes from Old English 'berere', from the verb 'beran' meaning 'to carry'.

'torch' developed from Latin 'torca' → Old French 'torche' → Middle English 'torche' and eventually modern English 'torch'. 'bearer' developed from Old English 'berere' (literally 'one who bears') through Middle English into modern 'bearer', and the compound 'torchbearer' arose in English by combining the two elements.

Initially it meant 'one who carries a burning torch' (literal), but over time it gained a common figurative sense meaning 'a leader or champion who carries forward an idea, movement, or tradition'.
