The names themselves
Meaning, roots, sound and the people who carried each
Where each name comes from
Kalani
the heavens, the sky; by extension, royal or chiefly
Hawaiian ka ("the") plus lani ("sky, heaven"). Because chiefs were spoken of in the language of the heavens, lani also carries the sense of high-born or royal, and the element appears throughout the names of Hawaiian aliʻi.
lani (Hawaiian: sky, heaven) → ka lani ("the heavens") → Kalani
How it traveled
Kalani comes straight out of Hawaiian, where lani — sky, heaven — is one of the most productive elements in the language of names, and ka is simply the definite article in front of it. In Hawaiian usage it belongs to men and women alike, as most Hawaiian names do; the language does not mark gender, and the same name is given to a son or a daughter without alteration.
Sunny
sunny — full of sunlight, bright with sun
The word is attested in English from around the fourteenth century, built on Old English *sunne*, 'sun'. Sunny also works as a short form of longer names — Sonia and Sonya, Susannah, the Norwegian Sunniva — and is widely used as an informal everyday name in India for men and women whose formal names are quite different.
sunne (Old English) → sunny (Middle English adjective) → Sunny
How it traveled
This is a vocabulary name: English took *sunne* from its Germanic roots, and by the Middle Ages had the adjective *sunny* for weather and, soon after, for people. For a long stretch it lived as a pet name rather than a legal one — the thing you called someone rather than the thing on their papers — which is the usual path for warm little words like this.

Out loud, and in short
Kalani
kah-LAH-nee
Hawaiian puts the stress on the second-to-last syllable, and every vowel is sounded fully: kah-LAH-nee. Outside Hawaiʻi you will also hear kuh-LAN-ee, with a flattened middle vowel.
- Lani — The most natural short form, and a standalone Hawaiian given name in its own right.
- Kala — Informal clip from the front; also used independently as a Hawaiian name.
- Kal — Casual, schoolyard-style shortening, mostly from English speakers rather than Hawaiian usage.
Sunny
SUN-ee
Stress on the first syllable, exactly like the weather word. It sounds identical to Sonny, which is where the spelling confusion comes from rather than from the pronunciation itself.
- Sunny — Already the short form: it serves as the everyday name for Sonia, Sonya, Susannah and Sunniva, and equally stands alone as a full given name.
- Sun — Informal clipping used within families rather than in writing.
- Sunnybear / Sunnyboo — Household-only extensions, of the kind short names attract from parents and grandparents.

The trade-offs, name by name
Kalani
Strengths
- The meaning is transparent and easy to explain in a sentence — ka, "the," plus lani, "sky, heaven."
- Spelled the way it sounds in Hawaiian, with no silent letters and no competing standard spelling.
- Comes with ready-made short forms, Lani and Kala, both of which stand on their own as names.
To consider
- Hawaiian names carry real cultural weight in Hawaiʻi, where lani names have deep genealogical associations. Families with no Hawaiian connection are sometimes asked about it, and it is worth being ready to answer plainly.
- Because it is genderless in Hawaiian and recorded mostly for girls on the mainland, a Kalani may occasionally be assumed to be a boy — on forms, in rosters, before anyone has met them.
- Expect some drift toward kuh-LAN-ee, and expect it to be mixed up with Kailani, Kalina and Leilani in writing.
Sunny
Strengths
- Everyone can already spell and say it — it is a common English word, so it needs no correction at the pharmacy, the airline desk or a new classroom.
- Two syllables, open vowels, no consonant clusters: it travels easily into languages that struggle with English sounds.
- Recorded for both girls and boys, so it does not have to be reassigned or adapted.
To consider
- Sonny is the homophone, and a lifetime of gentle corrections comes with the territory — spoken introductions will not distinguish them, and written ones often guess wrong.
- Word names invite commentary. People will make the obvious joke about weather or mood, including on days when a child would rather not hear it.
- Most children given this spelling are girls, so a boy called Sunny will occasionally be assumed female on paper — easily handled, but worth knowing in advance.
