Usage
What does mightily mean? Mightily means with might—great strength or power. To do something mightily is to do it in a strong or powerful way. Mightily is the adverb form of the adjective mighty, which means extremely strong (as in a mighty warrior) or powerful (as in a mighty king). Sometimes, mighty is used as a very informal way of saying very or extremely, and mightily can be used in a similar way to mean very or very much, as in I’m mightily impressed. This use of mightily can sound a bit old-fashioned or folksy. Example: He ruled mightily, and his empire extended to the ends of the earth.
