I'm looking for an adjective that would mean essentially the equivalent to the meaning some might ascribe to the made up word "vocabularic." Is there a word that means "of or applying to vocabulary?"
For example: "I hope this utilitarian endowment proves itself by aiding in the construction of constructs and the eschewing of [vocabularic] obfuscation."
I realize this word is found in some dictionaries, such Wiktionary, but I was wondering if a more general, scholarly, or accepted word is commonly used.
