What does allergy mean?
An abnormal reaction by the body to a substance, such as pollen, dust, or certain foods, resulting in symptoms like itching, swelling, or difficulty breathing. This reaction occurs when the body's immune system overreacts to a harmless substance.
Example
"She suffers from a severe allergy to peanuts and must avoid them at all costs."
