Growing up we've all called our Abuelitos "Buelo" or something like this. A lady at work is adamant that you spell "buelo" with a "W". I looked in an old Velazquez Spanish/English Dictionary that says "W" doesn't really exist in the Spanish language, exceptions are proper names that have no translation.
So help please
Buelo Vs Welo
Or is it just a matter of opinion?
