A USEFUL TOOL FOR YOUR WRITING EXERCISES.

Surfing the net I found a good Free Online Bilingual Dictionary that includes Word Magic Dictionary & Tools Professional (general reference English-Spanish bilingual dictionary), Medical Dictionary, the Law Dictionary, the Business & Finance Dictionary and the Computer & IT Dictionary.
The online bilingual Dictionary application here provided is a free service of Word Magic Software Inc. I think it is one of the most complete online bilingual and bidirectional English-Spanish dictionary on the web, showing not only direct translations but synonyms, complete definitions, set phrases, idioms, proverbs, usage examples, famous quotes and compound entries as well, all related to your entry word. On top of that, it offers English and Spanish pronunciation, separation into syllables and grammar attributes. It also accepts conjugated verbs and Spanish feminine and plural forms as valid entries.

Of course you can buy them as your personal software. There are probably many other benefits that are not covered here, as this program constantly changes, bringing us new ideas and additional solutions that help us on improving our English writing.

And please, don't think they are paying me for this advice.
