inspiratory

The word 'inspiratory' is built upon the Latin verb inspirare, meaning "to breathe into" or "to blow upon". This verb itself is a compound of the preposition in- ("into") and spirare ("to breathe"). The root spirare is central to many English words concerning breath and spirit, such as "respiration", "expire", and "spirit". The suffix -atory was added to form the modern English adjective, shifting the meaning from the action of breathing in to the quality or state pertaining to that action. Thus, the literal "breathe into" evolved into the specialized medical and physiological term describing the phase of inhalation.
