The Guardian· 30 Aug 2026

From Latin immortālis, from prefix im- (“not”) (from in-) + mortālis (“mortal”) (from mors (“death”), combining form mort- + adjectival suffix -alis), equivalent to im- + mortal. Displaced native undeadly, from Old English undēadlīċ. The term referring to the Persian soldiers was a Calque of Ancient Greek ἀθάνατος (athánatos). One suggestion claimed that "Immortals" were named by the ancient Greeks because wounded soldiers were quickly replaced, while another claimed that it was because Greek informants confused Old Persian anauša- (“immortal, without death”) with Old Persian anūšiya- (“companion, royal bodyguard”).
