[ Thesaurus ]

A thesaurus lists words in groups of synonyms and related concepts. Using a thesaurus on the word ‘thesaurus’ gives us synonyms and related concepts such as “vocabulary”, “glossary”, “phrasebook”, “word list”, and “lexicon”.

So, using a thesaurus on a word gives us a list of similar words and concepts, which might expand our understanding of the word.  

We can extend the concept of a thesaurus into communities; the words and language used matters. A community will have a common ground in language and sense-making, like a thesaurus provides. Communities and groups have in-built thesaurus-like boundaries, to structure and organise around.
