torch from (Middle English):
A torch in the original sense of ‘something soaked in an inflammable substance used to give light’ was often made of twisted hemp or other fibres. This is still the American meaning, and reflects the word's Latin origin, torquere ‘to twist’. Only in British English can torch describe a battery-powered electric lamp, which Americans call a flashlight. A torch song is a sad or sentimental song of unrequited love, whose name, used since the 1920s, comes from the phrase carry a torch for, ‘to love someone who does not love you in return’. The image in pass on the torch, ‘to pass on a tradition, especially one of learning or enlightenment’, is that of the runners in a relay race passing on the torch to each other, as was the custom in the ancient Greek Olympic Games. The Latin source of torch, torquere, is found in a large number of other English words. Most obviously it is the source of the engineer's torque (late 19th century), and the twisted Celtic neck-ring the torc (mid 19th century). Less obviously it is in contort (Late Middle English) ‘twist together’; distort (Late Middle English) ‘twist out of shape’; extort (early 16th century) ‘twist out of’; and retort (Late Middle English) ‘to twist back’ (the chemical apparatus gets its name from its twisted shape). Tortura ‘twisting, torment’ the Latin noun formed from the verb gives us torture and tortuous (both LME), and torment (Middle English). Thwart (Middle English) is an Old Norse word that goes back to the same Indo-European root.
The two words tortuous and torturous have different core meanings. Tortuous means ‘full of twists and turns’, as in a tortuous route. Torturous means ‘involving or causing torture’, as in a torturous five days of fitness training. In extended senses, however, tortuous is used to mean ‘excessively lengthy and complex’ and hence may become indistinguishable from torturous: something which is tortuous is often also torturous, as in a tortuous piece of bureaucratic language; their way had been tortuous and very difficult. The overlap in sense has led to tortuous being sometimes used interchangeably with torturous, as in he would at last draw in a tortuous gasp of air.
