IPA: /ˈɪnmeɪt/
KK: /ˈɪnˌmeɪt/
A person who is confined in a place like a prison or hospital.
The inmate was given a chance to participate in a rehabilitation program.
Inmate → It is formed from "in-" (meaning in or within) and "māns" (from Latin "manere", meaning to remain or stay). The word "inmate" refers to a person who remains or stays within a particular institution, such as a prison or hospital.
Think of someone who is 'inside' ('in-') a place where they 'stay' ('māns') — that's why an inmate is someone who stays in a facility.
