Survivor is formed from "sur-" (meaning over or above) and "vivere" (meaning to live). The word refers to someone who continues to live or exists after a difficult situation or event.
Think of someone who lives 'over' ('sur-') a challenging experience — that's why a survivor is someone who continues to live after hardship.
