Roget's Thesaurus is composed of six primary classes.[2] Each class is composed of multiple divisions and then sections. This may be conceptualized as a tree containing over a thousand branches for individual "meaning clusters" or semantically linked words. Although these words are not strictly synonyms, they can be viewed as colours or connotations of a meaning or as a spectrum of a concept.[citation needed] One of the most general words is chosen to typify the spectrum as its headword, which labels the whole group.
