IPA: /ˈɒstəmeɪt/
KK: /ˈɑːstəˌmeɪt/
A person who has had a surgical procedure to create an opening in the body for the discharge of body wastes.
After her surgery, she became an ostomate and learned how to manage her new lifestyle.
Ostomate → It is formed from "ostoma" (from Greek "ostoma", meaning mouth or opening) and the suffix "-ate" (indicating a state or condition). An ostomate is a person who has undergone an ostomy, which involves creating an opening in the body for waste removal.
Think of 'ostoma' meaning an 'opening' in the body, and the '-ate' indicating a condition — that's why an ostomate is someone with a surgical opening.
