Hi, I hope all is well. I wanted to know if I can use the nickname "El" for a friend? I want to make sure it is not considered saying Hashems name in vein. Thank you!

ב"ה Shalom As it appears in the Hebrew counterpart of this website, Rav Dov Lior Shlt"a wrote that since the intention is not to say G-d's name, there is no problem. And you may even call his name in the bathroom. All the best
