What are two ways words may be arranged in a thesaurus?

Words in a thesaurus can be arranged either alphabetically, making it easy to find synonyms and antonyms based on the initial letter of a Word, or thematically, grouping Words by related concepts or categories. Alphabetical arrangement is straightforward for quick reference, while thematic organization helps users discover Words that share similar meanings or contexts. This dual arrangement allows for enhanced flexibility in Word choice and usage.
