Ascribe means to give credit to, like if you ascribe the A you got on your group project to the hard work of your partners!
Ascribe's Latin root is ascribere, meaning basically "to write in.'' Makes sense, because ascribe is often used to link writers to their words. Many a quirky quote, like "Age is an issue of mind over matter. If you don't mind, it doesn't matter," is ascribed to that famous scribe Mark Twain. It can also be a way of blaming something — you might ascribe your bad attitude to your mom because she won't let you have cupcakes for dinner.
