IPA: /ɪˈmɔːrtl/
KK: /ɪˈmɔrtəl/
Not able to die or live forever; lasting forever without end.
Many ancient cultures believed in immortal gods who would never die.
A person or being that cannot die or is not subject to death, often associated with lasting fame or legendary status.
In many cultures, heroes are often seen as immortals who live on through stories and legends.
Immortal is formed from "in-" (meaning not) and "mortal" (from Latin "mortalis", meaning subject to death). The word describes someone or something that is not subject to death, hence, living forever.
Think of 'not' ('in-') being combined with 'subject to death' ('mortal') — that's why immortal means not subject to death.
