Read the FAQ explanation of Comprehensible InputReal Context
Contaminate is a verb used when something clean or safe becomes dirty or unsafe because of an unwanted substance or influence. You contaminate water, food, or a laboratory sample by introducing a contaminant, and you often say the item is contaminated by or contaminated with chemicals. The verb is distinct from pollution; contaminate emphasizes the act of introducing a contaminant into a specific thing, whereas pollute describes contamination of the environment more generally. The noun form is contamination, and in science or health contexts contaminate is common. Learners should remember the common prepositions and avoid confusing contaminate with pollute in casual speech.
Usage Reminders
- - Contaminate describes an action on a specific object.
- - Use with contaminated with/by for pollutants.
- - The noun form is contamination.
- - Do not use contaminate to mean general environmental pollution; use pollute.
- - In science, 'contamination' is a common term and 'contaminant' is the substance causing it.
Common Misconceptions
- Confusing contaminate with pollute; pollute is broader and for environments, contaminate targets specific objects.
- Thinking you can contaminate people; typically you would say infect or expose, not contaminate a person.
- Forgetting the prepositions is contaminated with/by and confusing them.
- Mistaking contaminant (noun) for contamination (noun) or vice versa.
- Using contaminate in place of ' contaminate the environment' when you should use 'pollute' or 'pollution'.
