Thesaurus

Thesaurus is one kind of dictionary, in concretely, of synonymous and antonyms. 
Today I want to examine the word  “Comunication”.
We can see a lot of synonymous:

The adequate word to choose will depend of the context.

Also we can see some antonyms, which are very difficult to know.

In conclusion, I think this entry will be useful to some teacher in order to grow up ther vocabulary.
