Does the word "God" denote something?
As background to the question, I've been reading Bertrand Russell's essay "On Denoting" were he makes the point about how there are statements/words/ideas which are meaningful—such as "the current king of France"—but don't actually refer to anything—where as "the current monarch of England" does. In other words, we can have words/phrases/ideas which seem to refer to something but do not actually denote (or in computer programming language "point" to) something.
In other words, "the Ground of All Being" is a meaningful idea, but is there an actual object to which such a title is referring to?
If there was ever a word that is more vague than any other, surely it's the word god.
Theists never agree about what their god is, even ones from the same religion.
Other "believers" in a god simply redefine themselves into being believers, like calling the universe their god like pantheists do.
Opinion would vary on what "God" would denote. Concreteness of the object being but one variance.
For myself, "God" would be meaningful, but only in the context of a fictional, superlative agent or as a given in the description of someone else's meaning within a context they would be referring to.
