The word accordingly is a good example of a subordinating conjunction?

This isn't the best example of a subordinating conjunction A subordinating conjunction starts a subordinating clause. Good examples would be: because, if, when, although, as long as. Once you as that to a complete sentence, that sentence can no longer stand on its own. For example:

Because I have added this word to my sentence, the clause is now a subordinating clause.

OR

If you are going to use a subordinating conjunction, accordingly is not the best word to use.
