Boys A

Aaron is a name of subtle contrasts: an unusual spelling that is easily recognizable; a solid Biblical choice that doesn’t feel exclusively tied to religion; a well-established name for boys but sometimes confused with the girls’ name, Erin; used internationally but with notably different pronunciations; classic like Andrew but not out of place with recent favorites like Weston or Jayden.

Abel, the name of Adam and Eve's unfortunate younger son, compensates with positive connotations: capable, competent, ready and willing.

Abraham is among the most classic baby names that's still widely-used today, popular for its references to both the Bible and American history. The Biblical Abraham was the first of the Old Testament patriarchs and is considered the founding father of the Jewish people. He was originally named Abram, until, according to Genesis, he was told, "No longer shall your name be Abram, but your name shall be Abraham, for I have made you the father of a multitude of nations."

Acacius is a Latinized form of the Ancient Greek Akakios and can be interpreted to relate to the same root as the name Acacia, for the thorn bush, or Akakios which means "not evil." With the modern taste for ancient names that end in "us," this obscure but attractive choice may have a chance of new life. Acacius is the name of three early saints.

No longer tied to the hapless Ace Ventura, this jaunty, high-flying nickname name is starting to take flight among celebrity and other parents, with its countless positive references to doing well in tests and poker games, on the tennis court and golf course, and in the air.

Acer is the Latin botanical name for the Maple tree. Where Maple feels quite feminine, Acer is a more masculine way to reference this tree.

The name of the great Homeric hero with the vulnerable heel, Achilles is more popular in its international form, Achille, which is popular in France, Italy, and Belgium. This variation did however appear briefly on the US Top 1000 list in 2015, perhaps owing to its similarity to the likes of Atticus, Adonis, and Apollo. It has declined in use since then, but is nevertheless chosen for around 160 babies each year.

Adam -- a primal Old Testament name -- was revived as a 1960s cowboy name. Adam is not as popular as it once was and feels ready for a respite, replaced by newer A names like Aidan/Aiden, Avery and Axel. Its most prominent current bearers include Adams Sandler, Levine, Brody and Driver -- who plays a character named Adam on Girls.

Adan is one of those names that feels familiar because it is in fact a variation of several other names. Used in Hispanic cultures, it is a form of Adam, more conventionally spelled with an accent as Adán. In English, it can be seen as a spelling variant of the uber-popular Aidan, Aiden, Aden, etc., while in Arabic, it is a unisex choice, and alternative form of Eden.

Adolf may have been a Swedish royal name but the terrible dictatorship of Adolf Hitler has ruled out this name Adolf for any sensible parent. In the US last year, there were more than 100 boys' given the Spanish variation Adolfo and a handful given the old school Adolphus, but none named Adolf or Adolph....thank goodness.

World War II stamped a permanent verboten on Adolph.

The name of a figure from Greek mythology, Adonis is a high-pressure name often synonymous with masculine beauty. Nonetheless, many mythological names that would have previously been deemed off limits have made their way up the popularity charts—for instance, Penelope currently ranks highly for girls. And indeed, Adonis was one of the fastest-rising boys' names of 2016, moving up 307 spots on the U.S. popularity chart in just one year.

Adrian is one of those names that’s easy to picture on all kinds of people. From an active and energetic five-year-old to your great grandpa, from the coolest, breeziest guy you know, to the quiet, serious one, it’s no wonder Adrian has always made the US Top 500 since the early 20th century.

This spelling variation of the much more popular Adrian entered reentered the Social Security list after an over 100 year absence in 1999. The -en ending makes it sound like the feminine Adrienne. We suggest sticking with the all A Adrian for your little boy.

Ajax was the strong and courageous Greek hero featured in Homer's "Iliad," known as Ajax the Great. But it's also the name of a foaming cleanser, and if you find that reference too strong, you might try the shortened Jax instead.
