Definition
Noun: A persistent, long-term inflammatory condition of the bronchi (the main air passages to the lungs) characterized by excessive mucus (sputum) production, resulting in a chronic cough and obstructed airflow.
Usage

It is often discussed in the context of respiratory health, smoking, and chronic obstructive pulmonary disease (COPD). * The primary symptom of chronic bronchitis is a productive cough that lasts for at least three months per year for two consecutive years. * Long-term exposure to irritants like cigarette smoke is a major cause of chronic bronchitis.
