If -logy is to the study of then what toward?

The suffix "-logy" means "the study of". There is no specific suffix that directly translates to "toward".

However, we can use prefixes to indicate direction or movement towards something. Here are a few options:

* "Ad-": This prefix means "to, toward, or in the direction of". For example, "adherence" means "the act of sticking to something".

* "Pro-": This prefix means "forward, in front of, or in favor of". For example, "proactive" means "taking action before a problem occurs".

* "Toward-": This is a direct word meaning "in the direction of".

So, while there's no perfect equivalent for "-logy" to indicate "toward", you can use these prefixes or the word "toward" itself to create a similar meaning.
