ELI5: Why is the word "used" pronounced differently with different meanings? Ex: I used the bathroom (yoozed) VS I used to go there (yoost).

Google doesn't seem to turn up anything. It boggles the mind.

It's not because the meanings are different, it's because of the word that follows them.  When "used" is followed by "to", it's easier to make a "t" sound at the end of "used". 

This is just us being lazy.
