What does the name Luke mean in Greek?

The name Luke comes from the Greek word "Λουκᾶς" (Loukás), which means "a man from Lucania". Lucania was a region in ancient Southern Italy.

However, the name Luke is also often associated with the meaning "light" because of its connection to the Latin word "lux" (meaning light).

So, while the literal translation is "a man from Lucania", the name Luke is often interpreted as meaning "light" due to its symbolic connection.
