<h3>What is a prefix?</h3>
The complete question is: When I told the doctor of my sinus pain and nasal pressure, she offered me a decongestant. Based on the prefix, de-, what does the word "decongestant" mean?
- a device that causes congestion
- a resource that defines congestion
- a way to measure congestion
- a substance that reduces congestion
A prefix is an affix word, letter, or digit that is placed before the beginning of the stem of the original word. These when added to the words change their original meaning and are generally the opposite.
Congestion in general means the stuffy feeling in the nasal passage. The prefix de- is used as the word that means off and when used before the word congestion will mean to be off from the stuffy feeling. Hence, the word decongestant is a drug that will treat and take off the feeling of congestion.
Therefore, decongestant means a substance that reduces congestion.
