Kailani
Feminine · Hawaiian roots · “sea and sky”
Kailani is overwhelmingly a girls’ name — 12,778 girls against 45 boys since 1880.
Kailani is built from two of the most productive words in the Hawaiian language: kai, the sea, and lani, the sky. Both turn up again and again in names — Leilani, Kalani, Noelani — so even ears that have never met this exact name recognize its shape. Said aloud it moves in four open syllables with the stress landing on the long middle vowel.

The story of Kailani
Hawaiian naming has long worked by composition — an inoa can be made new from meaningful words rather than inherited from a list, which is why kai and lani recombine so freely across generations. Hawaiian names traveled to the mainland US in the twentieth century largely through music and film; "Sweet Leilani," written by Harry Owens and recorded by Bing Crosby in the 1930s, carried the lani element into American ears well before Kailani itself appeared in national records. Kailani arrived on those records much later and has climbed slowly rather than in a burst. Its bearers in the mainland US skew heavily toward children.
Meaning
sea and sky, from Hawaiian kai (sea) and lani (sky, heaven, also royal, chiefly)
The two elements are not in doubt. How they are joined in English is looser: you will see it rendered as "sea and sky," "heavenly sea" and "sea of heaven," all fair readings of the same compound, since Hawaiian names are often meant to hold more than one sense at once.

Pronouncing Kailani
kye-LAH-nee
In Hawaiian, the vowel pair ai says "eye," so the first syllable rhymes with sky. Many American speakers default to kay-LAH-nee instead, which is why the Kaylani spelling exists; both are heard on the mainland.

- counting every spelling
The SSA counts spellings, not names. Kailani went to 1,215 girls in 2025, but Kaylani, Kailany and Kaylanni and the rest below are the same name said out loud. Together the 14 spellings went to 3,622, which makes it the 75th most-given girls’ name of the year — 178 places above the chart.
and 6 rarer spellings.
About 1 girl in 444 born in 2025 was given one of these spellings — against 1 in 1,323 for Kailani itself.
Spellings are grouped by a fixed rule that folds interchangeable English spellings of one sound (ck/k, ph/f, x/ks, a non-initial y for i) and keeps vowels apart, so Sean and Shawn stay separate names. It errs towards splitting: a family here is never larger than the truth. SSA national data, 2025. Method

The Jeannie test
Every popular name lives one long story — a climb, a peak, a slow settling back. Kailani's later chapters haven't been written yet, so we borrowed them: Jeannie climbed just as high around 1957, and its whole arc is on record. Line the two peaks up, and Jeannie's path sketches the road Kailani is walking now.

The trade-off
- The meaning is transparent in a living language — kai and lani are ordinary Hawaiian words, not a reconstructed guess.
- Two ready-made short forms, Kai and Lani, that both work as standalone names on their own.
- Sits inside a familiar family of names — Leilani, Kalani, Lani — so it is recognizable even where it is rare.
- Four open syllables with no consonant clusters, which makes it easy to say for speakers of most languages.
- The first syllable is genuinely ambiguous to American ears: kye or kay. Expect to correct it, gently and often, for life.
- Competing spellings — Kaylani, Kylani — mean the name will sometimes be written back to you the other way after you have said it aloud.
- This is a Hawaiian name with a real cultural home. Away from the islands it is worth being able to say where it comes from and what it means, which is a small thing to carry and an easy one.
- Kai as a short form is used widely for boys as well as girls, so the nickname reads less clearly than the full name does.
