Morphology

infective = infect (transparent) = infect + ive

Formed by the productive adjectival suffix '-ive' on the verb 'infect', meaning 'causing or capable of producing infection', which is directly derivable.

Etymology

Infective comes from Latin parts in- meaning 'into' and -fect meaning 'make', the same root you see in infect and infection. So an infective germ or virus is one that can 'make' disease go 'into' a person and so cause or spread infection.
