Morphology

infectious = infect (transparent) = infect + ious

The adjective is directly formed from the verb 'infect' with the productive adjective-forming suffix '-ious', so learners who know 'infect' or 'infection' can infer the meaning.

Etymology

The word infectious comes from the Latin word inficere, which meant 'to put into' or 'to dye', like putting colour into cloth so the colour becomes part of it. So an infectious disease is one that gets 'into' a person and can pass on to others.
