Lua

Lua is the Portuguese word for moon, descended from Latin luna. The Galician form is normally written Lúa, with an accent marking the vowel sequence. Both give the name a direct celestial meaning, with small spelling differences reflecting the conventions of the two closely related languages.

The same letters also appear in the name of an ancient Roman deity, but that is a separate historical route rather than another meaning every modern Lua must carry. A different modern association is the Lua programming language, which takes its name from the Portuguese moon word. For a family choosing Lua, the lunar image can stand on its own, connecting the name with night skies, changing phases, or a meaningful language tradition.
