3 Letter Boy Names

Lew is a masculine name that originated as a short form of Lewis or Louis. It has English and Scottish roots, derived from Germanic elements meaning 'famous battle' or 'renowned warrior.' 

The name gained popularity as a nickname but has also been used as an independent given name. While never among the most common names, Lew enjoyed modest popularity in the early 20th century in English-speaking countries. It has a classic, straightforward quality with a friendly, approachable feel. 

Britain's young Prince Louis has popularized the Louis version of the name, currently twice as popular as Lewis, with Lou given to about 70 baby boys in the US last year versus a dozen called Lew.

Short, simple international names like this make distinctive middle name possibilities. Nir also makes for a nature-oriented first name that's both straightforward and unusual. But be prepared for a lifetime of "...and far" jokes.

Rae as a masculine name has Scottish and Hebrew origins. It derives from the Scottish surname Rae, meaning "grace" or "deer," or it may be a shortened form of Raymond, meaning "wise protector." In Hebrew contexts, it could be related to the word "ra'eh" meaning "friend" or "companion." Though more commonly used for girls in recent decades, Rae has a history as a male name, particularly as a middle name or nickname. Its single-syllable simplicity gives it a strong, straightforward quality appreciated by parents looking for a minimalist name option. The name carries a gentle yet masculine energy and works well in combination with longer first names. As a standalone male name, Rae remains relatively uncommon, giving it a distinctive quality.

Popularized in Scotland by Tam O'Shanter, the hero of one of Robert Burns' most famous poems, it's associated in the U.S. with the plaid cap he gave his name to. But this could make a creative honor name or middle name after an ancestral Thomas.

Tau, rhyming with cow, is a simple straightforward name with roots in two languages and cultures, the Kaurna language spoken by indigenous Australian people or the African Tswana language, a Bantu language spoken by five million people.
 
Grimes and Elon Musk have a son named Techno Mechanicus, who goes by Tau — a more wearable nickname than their other children, X and Y.

Tod is a masculine name of German and English origin, meaning 'death' in German or functioning as a short form of the names Theodore ('gift of God') or Todhunter. Despite its somewhat grim German meaning, the name has enjoyed moderate popularity in English-speaking countries. Tod peaked in usage during the mid-20th century but has since declined. The name carries a strong, concise quality with its three-letter simplicity. Famous bearers include American actor Tod Andrews and baseball player Tod Sloan, which helped establish it as a recognizable yet uncommon choice. Tod's brevity gives it a straightforward, no-nonsense character.

Notably borne by Umi-a-Līloa, a fifteenth century supreme ruler or high chief of Hawaii, Umi is comes from the word for "tenth". The legendary king was considered just and responsible for uniting the Hawaiian island, having come into power after killing his brother, to end a brutal reign.
 
While Umi is a masculine Hawaiian name, it is a feminine choice from its Japanese and Indonesian roots.

This spelling pares Will down to the bare minimum — and why not? It is also a Welsh diminutive of William / Wiliam / Gwilym.

Russian-born actor Yul (christened Yuliy) Brynner gives this short name a strong, steely image.

Rig is an uncommon masculine name with multiple possible origins. It may derive from Old Norse, where it was a name for the god Heimdall in the Eddic poem Rígsþula, making it a name with mythological significance. Alternatively, it could be a short form of Rigby or similar names. In Sanskrit, 'Rig' appears in 'Rig Veda,' one of the sacred texts of Hinduism. The name has a distinctly concise, strong sound with just one syllable. Its brevity gives it a modern, punchy quality despite its ancient origins. Rig remains extremely rare as a given name, appealing to parents seeking something truly unique with historical connections.
