Dictionary/ Thesaurus

[Gonk]

Does anyone know any good online ones? The ones I've found so far a rubbish and full of adverts.

[Mike Carroll]

Wiktionary is a pretty good dictionary, though its thesaurus is rather weak. No ads, though, and it loads fast!

Thesarus.com does what the URL says, and does it very well. Ads aren't too intrusive most of the time, but the layout is a bit annoying.

Merrian-Webster is very strong on both counts, but it's packed with ads.
