Corollary describes a result that is the natural consequence of something else. You could say that your renewed love of books is a corollary to the recent arrival of a book store in your neighborhood.
The noun corollary describes an action’s consequence, such as having to study more, a corollary to getting a bad grade. The word is often seen with the prepositions “to” or “of,” as in “a corollary to fortune is fame.” Math enthusiasts may already be familiar with the word corollary, which can be used more formally to describe a new proof or proposition that follows naturally from an established one.
(logic) an inference that follows directly from the proof of another proposition
a practical consequence that follows naturally
