Lexicography

I'm sitting here on the red line thinkin about a lexicographical study in Romans 4:14. Is it true lexicographical studies exist to expose errata in the various lexica that we in NT studies survey?   If so I hope that this term for "null," does not return to me void. Lol. Anyway I have not utilized this venue enough hopefully I can be more consistent with posting random thoughts and ideas about the NT here.
