Meaning

Sea in the Hawaiian account; other name routes differ.

The exact English entry records a Hawaiian kai, sea, explanation in US use. European short-form traditions are separate and do not inherit this gloss. The licensed Scottish Fire account is not corroborated or selected here.

Origin

European short-form and Hawaiian accounts; earlier European history uncertain.

The source discusses Danish Kaj, a possible Roman relationship, German/West Frisian pet-form accounts and a Hawaiian word-name explanation. Possibilities remain qualified; no one route is assigned to every Kai.

English pronunciation

/kaɪ/

Directly recorded English pronunciation of the exact given-name spelling. The IPA is labelled Canadian English. The entry documents given-name use with several possible cultural histories; this reading does not select a universal origin. The plain-text guide is approximate; a bearer’s preferred reading can differ. No audio reused.

Recorded English reading, as published. Accents and preferred pronunciations can differ.

Published name usage

Counts apply only to the exact spelling, place, year and recorded usage shown. Places are separate; these figures are never added into a worldwide total. Missing or suppressed records never mean zero.
