Relating to a substance that helps to break down mucus in the body, making it easier to expel.
The doctor prescribed a mucolytic to help clear the patient's airways.
Mucolytic → It is formed from "mucus" (from Latin *mucus*, meaning slime or mucus) and "lytic" (from Greek *lytikos*, meaning able to dissolve or loosen). The word "mucolytic" refers to a substance that is able to dissolve or loosen mucus.
Think of a substance that helps to 'loosen' ('lytic') 'mucus' — that's what mucolytic means.
