I don't know if language is the ultimate reality. That strikes me as bogus. In principle, I can agree that every experience is mediated on some level, but I'm wary of that being a linguistic one. Maybe it is for some people. It certainly seems to be for deconstructionists. :)

This short of thing always makes me think of Through the Looking Glass:

"When I use a word," Humpty Dumpty said, in a rather scornful tone, "it means just what I choose it to mean -- neither more nor less."

"The question is," said Alice, "whether you can make words mean so many different things."

"The question is," said Humpty Dumpty, "which is to be master -- that's all."
