We would like to recommend some useful aids on the internet that are really helpful when you write English, especially if you are not a native English speaker. This is written by me and my friend Ewa, visit her blog at: www.englishewa.blogspot.com !
We tried out many different dictionaries, and we found two that we really liked. Both of them are easy to use and understand, and they had good explanations of words. The two dictionaries we chose are http://dictionary.cambridge.org , and http://www.thefreedictionary.com .
The first one was the one we liked the most. It has many different explanations of the word you search for, with examples. We also liked the design of the website, because it is very well structured. You find what you look for immediately. It is also possible to choose between different varies of English, like British English, American English and Business English. There is also a Spanish – English/English – Spanish dictionary, which is great for us who learn Spanish in school.
The other one was also quite good, but I don’t think that it is just as good structured than the first one. It contains fewer explanations and options.
We have also checked out Britannica online, and it seems like it has a lot of common with Wikipedia. But, it looks better and more credible, and we will probably use it for school.
