I have absolutely no connection with this resource, financial or otherwise, but have found it to be useful.

It's designed to help you when you have a word on the tip of your tongue and cannot quite remember it. It works by asking you what you know about the word such as what it starts with, how it ends, what it means or what it sounds like.

As you fill in the boxes it suggests words that might match your answers. Obviously the more boxes you complete, the shorter the list of matches.

Appropriately enough it's called Tip Of My Tongue.
