Spend a moment with the Visual Thesaurus, you'll be glad you did. You put in a word, it shows you a network of words related to it, grouped like a mind map so similar kinds of words are together. Then you can click on a sub-network and delve further. I tried coach (and got the word in its transport sense as well as the sporting sense). delving further it a got into words like apprize (and apprise), and teach and learn. Maybe useful for writing marketing copy or updating your web site (which is, of course, marketing copy!)
