Morphology

infect = in + fect

Although historically analyzable as in- + -fect, '-fect' is a bound combining form (not a standalone English word), so a typical B1 learner cannot derive the meaning from its parts.

Etymology

Infect comes from Latin parts in- 'into' and -fect 'make', so it gives the image of putting something inside a person that makes them sick. That's why infect means to cause illness by spreading germs or viruses.
