All built-in Mathematica objects have names that begin with an
uppercase letter. Consequently, anything that begins with a
lower case letter is an object created by the user and means
nothing to Mathematica beyond the definitions set by the user.
So, both "pde" and "bc" are user created objects.

The fact all Mathematica built-in objects start with uppercase
letters is really very useful. This ensures any name you use
will not conflict with any built-in objects if you adopt the
convention of always naming things you create starting with a
lower case letter.
