Thesaurus

A thesaurus is a reference work that lists words grouped together according to similarity of meaning (containing synonyms and sometimes antonyms), in contrast to a dictionary, which contains definitions and pronunciations.

The largest thesaurus in the world is the Historical Thesaurus of the Oxford English Dictionary, which contains more than 920,000 entries.

Librarian: It's at the "reference" or the "non-fiction" section.

Girl: OK, thank you~

Thesaurus

A very difficult word to pronounce. Usually ends up 'thathauruth' or a variant of it. However, one can easily overcome this obstacle by pronouncing the word very slowly. See thathafrath.
