Morphology

contaminate = contamin + ate

The suffix '-ate' signals a verb meaning 'to make X', but the stem 'contamin-' is not a standalone English word and is not transparently analyzable by average learners, so the overall relation is only partially clear.

Etymology

Contaminate comes from the Latin contaminare, with con- meaning 'together' and the idea that things 'touch' or 'mix' and make each other unclean. So to contaminate something is to let harmful things 'touch' or mix with it and make it dirty or dangerous.
