Common mistake:
Learners sometimes confuse "contaminate" with "pollute" and use them interchangeably. "Pollute" is more common for environmental problems in general, while "contaminate" often highlights that a specific thing (water, food, blood, sample) has been made unsafe by a particular substance. Another common mistake is using the wrong preposition: it is usually "contaminate [something] with [substance]", not *"contaminate [something] by [substance]" in this core sense.

Common mistake:
Learners sometimes think this figurative sense is always physical and try to use concrete objects as the thing that is contaminated. In this meaning, the object is usually abstract, like "minds", "culture", "process", or "debate". Also, do not say *"contaminate someone to bad ideas"; use "contaminate someone with bad ideas" or "contaminate their thinking".
