Define pharyngitis?

Pharyngitis is the medical term used to describe inflammation or irritation of the pharynx, which is the part of the throat located behind the mouth and nasal cavity. It is commonly referred to as a sore throat. Pharyngitis can be caused by various factors, including viral or bacterial infections, allergies, or irritants.
