What does the name Kael mean?
Kael has no settled origin in the dictionaries we checked, and Wiktionary has no entry for it as a given name. Wikipedia describes it as Irish, from caol 'slender', and connects it with Kellen, but cites no source; caol is a real Irish word meaning 'thin, slender', but no Irish personal name Kael is recorded in our references. It is best treated as a modern name of undocumented origin.
How sure is this? Not documented. The Irish 'slender' explanation is unsourced and unconfirmed.
Other explanations you may read: Irish, from caol 'slender'.
