It's important to note that the word "Moorish" has a complex history and can be considered a potentially offensive term in some contexts. It's best to avoid using it unless you're specifically discussing its historical use in relation to the Moors, a Muslim people who ruled Spain from the 8th to the 15th centuries.
When referring to the name Mauro, it's best to simply describe it as "of Italian origin" or "meaning 'dark-skinned'" to avoid any potential misunderstandings.
