Without a claim; having no legal right to something, or not making or possessing any claim.
From claim + -less (Old English suffix meaning 'without' or 'lacking'). The -less suffix is one of the most productive in English for creating opposites.
The -less suffix is so powerful that you can add it to almost any noun to mean 'without that thing'—claimless, hopeless, homeless, clueless—and English speakers instantly understand what you mean, even if they've never heard the word before.
