What does inspiratory mean?
Inspiratory is an adjective most often used in medicine and physiology to describe breathing in, or inhalation. It commonly appears in expressions such as “inspiratory muscles,” referring especially to the diaphragm and other muscles that expand the chest and draw air into the lungs, and “inspiratory capacity,” meaning the greatest amount of air that can be inhaled after a normal exhalation. In broader literary use, inspiratory can describe something that inspires, encourages, or stimulates the imagination, though this sense is less common. The word is a technical counterpart to “expiratory,” which refers to breathing out. It is precise rather than conversational, but understanding it is useful whenever reading about respiration, respiratory illness, or speech and vocal technique.
