In general usage, 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 provides definitions for words, and generally lists them in alphabetical order. With this tool a poet can create a consistent meter in his poem,
The speaker in "Stopping By Woods on a Snowy Evening" treats his horse kindly; in "Chura and Marwe," Marwe chooses Chura for her husband although he is ugly.
