You only get it if your name is exactly the same as the built-in name. 2) You could Unprotect the symbol name, then overwrite your definition on top of it. This may have unpredictable results if other mathematica symbols depend on the one you just overwrote. I don't recommend this option. 3) Since all mathematica symbols start with a capital letter, you could start yours with a small letter.
