What does immortal mean?
Immortal means living forever or lasting permanently. In its literal sense, it describes a person, being, or soul that cannot die, as in references to the gods or to beliefs about the afterlife. Far more often, it is used figuratively for things that endure beyond a particular time: an immortal legacy, an immortal reputation, an immortal work, or an immortal contribution. The word suggests not merely long-lasting value but exceptional permanence and significance. It comes from the Latin immortalis, formed from in-, meaning “not,” and mortalis, meaning “subject to death.” Although immortal is firmly associated with religion, mythology, and literature, its figurative use is common in ordinary speech and formal writing. When applied to fame or achievement, the term often implies that someone or something will be remembered for a very long time, perhaps indefinitely.
Not subject to death; living forever.
"The poem describes a garden inhabited by immortal spirits."
This literal sense occurs especially in religious, mythological, and literary contexts.
Enduring permanently, especially in reputation, achievement, or cultural significance.
"The scientist's discoveries left an immortal mark on modern medicine."
This figurative sense is especially common in expressions concerning legacy, fame, and influence.
From Latin, “immortal” literally means “not mortal”; today it describes both lives that never end and legacies that outlast their creators.
