Slender or thin
Cail is a rare masculine name of Gaelic origin, derived from the word 'caol' meaning slender. It is often considered a variant of the more common Cale or a shortened form of names like Caleb or Cailan. In modern usage, it appeals to parents seeking a short, punchy, single-syllable name with Celtic roots.
