I would like to share with you a new tool for enriching our vocabulary and our students one. It is called Lexipedia http://www.lexipedia.com/ and it is a visual tool for learning languages, a mixture of a dictionary and thesaurus, which provides a visual net of semantic relationships and it is free. Besides when you introduce a word it doesn�t give you only the meaning but you can also listen that word pronunciation. I hope it is useful for you and you like it!!
