Kai is an internationally flexible name with many possible origins and meanings, growing in popularity in the US and a diverse range of European countries.
 
In the US, the name Kai is most commonly referred to as being of Hawaiian derivation, meaning "sea." In Europe, Kai is largely considered to have Frisian origin as a diminutive of the name Kaimbe, meaning "warrior", or as a short form of Gerard "brave spear". 
 
Kai is also found as an independent name in African, Chinese, Turkish and Native American cultures. Kai is a strong, evocative multi-cultural name that packs a lot of power in its single syllable. 
 
Famous as the name of the boy enchanted by the fairy-tale Snow Queen, Kai was chosen for her son by actress Jennifer Connelly and as a middle name for son Samuel by Naomi Watts and Liev Schreiber. 
 
Kai is popular with Berries as both a first and middle name choice. Perhaps because of its international familiarity, Kai is popular in video games. Its most prominent namesake is Danish-born jazz trombonist Kai Winding.
 
Kai ranks in the US Top 1000 for girls, but is used more than 90 percent of the time for boys. Donald Trump, Jr. has a daughter named Kai Madison and Gigi Hadid and Zayn Malik named their daughter Khai in 2020.

Lucinda, an elaboration of Lucia created by Cervantes for his 1605 novel Don Quixote, is a pleasingly pretty alternative to Lucy. It was subsequently used by Moliere in his play The Doctor in Spite of Himself' (1666). More in tune with the times than Linda, Belinda and Melinda, it could be used to honor someone with one of those dated names. 
 Lucinda was a Top 200 name in the late nineteenth century, but hasn't been on the charts for more than 25 years--which could make her ripe for revival.
 One appealing namesake is country-rock-blues singer Lucinda Williams. Similar in feel: Lucilla and Lucetta.

Unique Names I may use or did use for Things

A lot of these names are ones I made up, the ones I didn't were accidental or I thought that they deserved to be here. 
Some of these names aren't very good, and the only reason they're here is because I made and used them at some point.
