If you know of any good websites or run one yourself, feel free to recommend it. I cannot promise to look at all of them but if I find your site suitable for my weekly feature then I will do my utmost to accommodate it. In return I might merely ask that you link to my blog. But please (and I mean this in the politest possible terms) do not ask me to advertise your commercial service.
This week’s offering is Synonym Finder. It does exactly what it says on the tin. Have you ever written something and when you have gone back through to read it you realise that you have repeated the same word six or seven times in the same paragraph? Aside from a complete rewrite, if you think it is succinctly written then the best thing you can do is find a synonym using either a thesaurus but for quick reference, a website like this.
This website is pretty clever/ingenius/smart in that it gives you not only several synonyms but also a definition and an example of usage. The site also has antonyms along the top menu (meaning the opposite of what you have put in) including definition and examples of usage.
