To avail means to take advantage of an opportunity, the way you'd be crazy not to avail yourself of a chocolate milkshake on Free Milkshake Day at your local ice cream parlor.

Sometimes avail is used to mean "help," and in that case it can be used in a sentence like "Nothing seemed to avail me, not even winning the lottery." More often though, avail shows up in the company of "oneself of," as in the sentence, "I hope you avail yourself of my advice, because I'm very wise." It might seem like a complicated way to use a verb, but it's one you should avail yourself of if you're hoping to impress someone.
