Mortan is not a standard English word. It is most often a proper name (first or last name). Depending on origin, its meaning may be:
· Scandinavian (Faroese/Icelandic): A variant of Martin, from Latin Martinus ("of Mars," the god of war) → meaning "warlike" or "dedicated to Mars."
· English variant: Possibly a variant of Morton, meaning "settlement by the moor" or "town near the wasteland."
Note: In Esperanto, mortan is the accusative case of morta, meaning "dead" or "death." So the word also has a direct reference to death in Esperanto.
