Why do you translate English word James into Spanish Santiago?

The Spanish name "Santiago" is the equivalent of the English name "James". It's not a translation, but a cognate, meaning they share a common origin and are essentially the same name in different languages.

Here's why:

* Latin origin: Both "James" and "Santiago" come from the Latin name "Jacobus".

* Evolution of names: Over time, "Jacobus" evolved into different forms in different languages. In English, it became "James", while in Spanish, it became "Santiago".

So, while they are spelled and pronounced differently, "James" and "Santiago" are considered the same name with different linguistic expressions.
