It is a conjunction. (Click link for second grade grammar lesson if you are unfamiliar with conjunctions). It's definition, according to Webster's dictionary, is

Or - Definition and More from the Free Merriam-Webster Dictionary
You'll also note that the defintiion itself uses "or" twice in the "equivalent or substitutive character of two words or phrases" fashion since "equivilant" and "substitutive" have an equivalent or substitutive character, as do "approximation" and "uncertainty". This can be used to assist your in comprehending what it was that you actually asked, since there is no comprehension of your own question evident from your responses.
But here's the kicker, regardless of which definition you seek to plug in, neither allows you to weasle your way out of the fact that the question was adequately answered as asked.
So I retract the intellectually dishonest question, seeing as you clearly did not understand what the word "or" means.
Intellectual incompetence is not the same thing as intellectual dishonesty.
