Antonyms are words that are opposites in meaning. For the term "lung capacities," antonyms include "lung disabilities," "lung dysfunctions," "lung disorders," and "lung impairments." These antonyms describe the opposite of having adequate lung function and capacity. They denote various respiratory conditions, such as asthma, bronchitis, emphysema, pneumothorax, and pulmonary fibrosis, which can affect the ability to breathe properly. Unlike lung capacities, which refer to the volume and functioning of the lungs, these antonyms depict the negative impact on lung health and the associated symptoms, such as coughing, wheezing, shortness of breath, and chest pain. Therefore, understanding antonyms is crucial to expanding one's vocabulary and communication skills.
