"A simple way to remember the meaning of avow is that it sounds and looks a whole lot like \"a vow,\" to which it's closely related. At the end of almost every wedding, the couple takes their vows, in which they avow their commitment to each other. To take a vow is to avow the things that you say in that vow. Be sure that you mean what you say when you avow something, because people will hold you to it. And don't mutter or mumble. That's no way to avow something."
