IPA: /ɪnˈheɪləˌtər/
KK: /ɪnˈheɪlətər/
A device that helps a person breathe by delivering a mixture of gases, often used in medical situations or for people with breathing difficulties.
The doctor gave her an inhalator to help with her asthma during the attack.
Inhalator → It is formed from "in-" (meaning into) and "halare" (meaning to breathe). The word describes a device that helps to breathe in medication or air.
Think of breathing 'into' ('in-') something that helps you 'breathe' ('halare') — that's what an inhalator does.
