Male slovenian name.
There is no real origin of the name Aljaž. The name is mostly used in Slovenia.
Because Slovenia is a christian country, the name could come from the biblical names like Elias or
Elijah and was later translated into slovene in the same way as did the names for example;
Mathew - Matjaž or Thomas - Tomaž.
The name Elijah in Hebrew (אֵלִיָּהוּ – Eliyahu) components ; El (אֵל) = God and Yahu (יָהוּ) = short form of Yahweh (the name of the God of
Israel) and together meaning Eli-yahu = My God is Yahweh
