Morphology

speed + demon

The phrase combines the clear noun 'speed' with a metaphorical use of 'demon' (an intense or obsessive person) to denote someone characterized by excessive speed, so the overall meaning is largely derivable from the parts. However, this relies on the learner recognising the figurative extension of 'demon' beyond a supernatural being; a B1 learner who only knows the literal sense may not immediately infer the habitual, dangerous-driving nuance.

Etymology

Speed demon probably comes from a simple picture: a wild demon moving with great speed, like a tiny creature racing down a road. People used 'demon' for someone wild or extreme, so today speed demon means someone who 'drives very fast'.
