Morphology
pyrogen = pyro + gen
The word is built from scientific combining forms meaning roughly 'fire/fever' and 'producing', but the medical sense 'fever-causing substance' is specialized and not readily inferable for an average learner.
Etymology
Pyrogen combines pyro- 'fire' and -gen, like in generate, 'to make'. So a pyrogen is literally something that 'makes fire', which helps you remember it as a substance that makes the body heat up or causes a fever.
