This Ethiopian boy name looks like a shortening of popular Addison, but has separate roots. Nonetheless, with Addison's popularity, Addis would fit in while standing out as a boy's name in English-speaking countries.

Aitana is the name of a Spanish mountain used by the poet Rafael Alberti for his daughter. He reportedly chose it because the mountain was his last glimpse of Spain when he went into exile after the Spanish Civil War. The name was popularized by Aitana Alberti's goddaughter and namesake, actress Aitana Sanchez-Gijan. It became one of the fastest-rising girls names in 2016, after entering the US Top 1000 in 2015, and is among the most popular <a href="https://nameberry.com/baby-names/495/spanish-names-for-girls">Spanish names for girls</a> in its native Spain and beyond.

The surname-style Alden has been on the rise in the US in recent years, while tree-inspired Rowan is a top choice. Combine this with the popularity of names ending in -er such as Carter and Parker and it makes sense why Alder is now 4 times as popular as it was a decade ago. Given to 125 boys in a recent year, it could be a modern way to honor an "Al". 
 
Deriving from an old English surname or from the alder tree, whose wood is used to make electric guitars, Alder can mean "old" if considered a variation on the Germanic alter or "red, brown" when you follow the root of the tree name.
 
Sometimes said to symbolise regeneration, resurrection, and life thanks to the ability of the alder tree to regrow quickly, thrive in inhospitable land, and bleed red sap, Alder is a name to watch out for.

Alder

Astrid has been a Scandinavian royal name since the tenth century, and many people associated it with the Swedish author of the Pippi Longstocking stories, Astrid Lindgren. Astrid is derived from the name Ástríðr, which is made up of the Old Norse elements that mean "god" and "beautiful." 
Related names include Asta, a diminutive used throughout Scandinavia, and Astride, the French form. Despite their similarities, Astrid is unrelated to Astra, a Latin name meaning "of the stars."
 
Astrid has never really assimilated into our culture the way Ingrid did, but with the renewed interest in international names, Astrid might be worth consideration by parents with Norse roots. 
 
Astrid is the name of the teenage heroine of Janet Finch's 1999 novel White Oleander and has appeared as a character in How to Train Your Dragon and the TV shows Fringe and Once upon a Time.

Aya, barely more than a breath, is an international favorite, with origins in several languages and cultures. Popular throughout Europe, It debuted on the US Top 1000 in 2012.
 In the entertainment industry, Aya has two international bearers: Aya Korem, an Israeli singer-songwriter, and Aya Liu, a Taiwanese actress. And actress Hilary Swank named her twin daughter Aya (and her son Ohm).
 
As with many multicultural names, it has a variety of meanings. In Japanese, it is a colorful name, also associated with intricate design. From its Hebrew origins, it can be considered a nature and bird name, related to the honey buzzard or to birds and flying more generally.
 
Aya is also a Danish name (a respelling of Aja or Aija) possibly meaning "rock, lull" from Latvian Aija or "happiness" from Finnish Eija, and is a highly popular choice there. In Arabic meanwhile, Aya means "sign, evidence" or "verse" and is a popular name in the Muslim community.
 
That only scratches the surface, however, because Aya also appears in Semitic mythology, where it means "dawn"; as a Kazakh name meaning "hideout, shelter"; in the Cherokee language meaning "I, me"; and as an alternative form of the Basque place name, Aya.
 
Thought we were done? No, because Aya may also be linked to the Turkic element ay meaning "moon", and therefore to Turkish-Altaic mythology in which the angelic Ayas symbolized creativity, abundance, and goodness. 
 
In Mongolian, it means "melody", while in in Baoule on the Ivory Coast, it is given to girls born on Fridays.
 
An Ancient Egyptian Queen, a Belgian Catholic Saint, and an Akkadian goddess, Aya has a lot of history and meaning hidden behind those three letters.

Spelled with either one 'l' or two, Calista came to the fore in 1997 when Calista Flockhart hit it big as Ally McBeal. Flockhart, who bears her mother's middle name, didn't just introduce a name, she introduced a whole sensibility. Pretty and delicate, Calista is definitely worthy of consideration, especially for parents with Greek roots. 
 In ancient myth, Calista (or Calisto)was a nymph loved by Zeus, whose jealous wife Hera turned her into a bear.
 
Nicknames Callie (or Cali), Cassie, Calla, Issy, Lissy, or Kit add extra appeal.

Calista

Rugged but gentle at the same time, Cassian is a saintly and stylish choice that was derived from the name Cassius. Before 2017, it was an obscure choice, given to a tiny handful of boys each year. As of 2023, however, it's become one of the top ten fastest-rising names in the US, more than doubling in usage since 2022 and edging closer towards the Top 500.
 There are a number of fourth and fifth century St. Cassians, one of whom is the patron saint of stenographers (though he must not get much work these days).John Cassian was a monk and ascetic writer who introduced Eastern monasticism into the West; Cassian Elwes is a British film producer, and Patrick Wilson used the alternate spelling Kassian for his son.
 It is unlikely however, that any of these can be credited for the rise of Cassian. Instead, we must turn to pop culture.
 In 2016, just before Cassian began to climb the charts, the Star Wars Franchise movie, Rogue One, was released and included a character called Cassian Andor, who then went on to feature as the lead in the television spinoff series, Andor. With the sounds of popular Julian, Jasper, and Adrian, like Casper but not too ghostly, Cassian caught people's attention, not just in the US, but in the UK, where it now ranks in the Top 600.
 
But what caused the even bigger leap up the charts in 2023? Again, we must look towards a fictional character. The popular romance-fantasy book series A Court of Thorns and Roses by Sarah J. Maas features a Cassian, and the latest novel included a Cassian storyline that likely put the name on people's radar. "ACOTAR" as it gets called is popular on BookTok and BookTube so it's no wonder parents are taking inspiration from it. 
 Similar to Nameberry favorite Caspian with sounds that are both strong and soft, both ancient and right up to date, Cassian is a hot name right now, and was given to more than 550 babies in 2023.
