Without an heir; having no designated successor or inheritor for a title, property, or position.
From 'heir' (Old French 'eir,' Latin 'heres') plus the suffix '-less' (Old English 'leas' meaning without or lacking), creating an adjective describing the absence of heirs.
A 'heirless' death was historically a catastrophe for kingdoms and families—it's why some monarchs had multiple children and why succession laws became so elaborate and complicated.
