Guide to Grammar and Writing will help you with most of the basic stuff of writing. Large clear print, well-organized information, and good examples and explanations make this a valuable writer's tool. Highly recommended.

The Web of On-Line Dictionaries is incredible. Languages, specialized fields, neologisms, just about any word is here! (Except, of course, the word I was looking for that led me to discover this web site.) You'll love it!

Collective Names of Animals is a useful resource for a narrow topic. What do we call a group of badgers, of heron, of magpies, of foxes? (Not in correct order, it's skulk, cete, seige, and tiding. But you knew that.)

Word Central is Merriam-Webster's dictionary site for kids. The definitions are easy to understand, there are some language games, and it's well-done.

AllWords.com is yet another dictionary site. One helpful feature here is the "crossword helper" that lets you supply whatever letters you have and then it looks for all the words that might fit. Could free up a lot of time on Sunday mornings for you! It will translate the word into several languages, if you like. It also has links to a math site, a lottery site, and goodness knows what else.

Wilton's Etymology Page is a hobby site that I really like. It doesn't have everything, but if you're wondering where some funny words and expressions came from, you'll find some interesting ideas about many of them here. Great fun to read on a rainy afternoon with no word in mind.

Famous Quotations Network  will help you find something brilliant that someone else said on almost any topic. A great way to start an essay or speech.
