Oh, good grief, if I had thought that through I would have realized December is several months away, so ‘thusly’ (I don’t imagine that is a word, is it?) two years.

I have long thought that thusly was a word. Could two such brilliant people possibly be wrong? What is the likelihood of that? Irregardless(!) of my certainty, I decided it is best to look it up to be certain.

I looked it up in my Oxford Dictionary and Thesaurus, edition 1996, which resides on the second shelf above my desk. I saw thus is an adverb. Therefore, the -ly suffix is a bit redundant. Nevertheless, I kept looking. Ah ha! IT IS A WORD! It is listed as a colloquial adverb. It has made it into modern usage and is listed as proper.

Thusly, it is fine to use THUSLY.
