Hey, I'm making a Web Based anagram game for fun and practice. The game presents the player with a word and the player needs only to construct new words out of letters contained in the given word. Where I am running into trouble is spellchecking the submitted words for validation purposes.
I initially thought that this would be fairly trivial, and my first solution was to just copy the dictionary file that is located at usr/share/dict and compare the submitted answers to the words in that file. This however fails when dealing with different forms of a word. For instance, the dictionary has the word "ask", but if the user were to enter the word "asks", it would be considered wrong.
Knowing that I can't hope to write a functional spellchecking algorithm (nor do I want to spend the time trying to tackle that) I thought that I may be able to use the browsers built in spell checking capabilities. But my searching for an answer to this hasn't produced any useful results.
Is there a way to use the browsers spellchecking capabilities, perhaps using javascript or something? And if not, how might I best approach this problem?
Thanks!
JavaScript spell-checking libraries do exist. I ran across this a little while ago: http://www.chrisfinke.com/2011/03/31/announcing-typo-js-client-side-javascript-spellchecking/
John Resig (of jQuery fame) recently wrote a series of blog posts about fast spell checking for a Javascript-based anagram game he's working on.

You might be able to skip to the last one where he wraps up all his findings there. It is quite in depth, measuring up look-up speed, download time, initialization time..
I've used JSpell Evolution before. Once you get past the annoying installation/setup process, it works pretty well.
There are plenty of free dictionaries online that include plurals, hyphenations etc.
E.g. a quick Google search found these dictionaries which support the spell checking functions of OpenOffice.
Have a Google. You can always aggregate several dictionaries into a massive super-dictionary!
Have fun.
