What is Merriam-Webster?
Merriam-Webster is a U.S.-based company established in 1831, renowned for its dictionaries and reference materials. It operates as a subsidiary of Encyclopædia Britannica, Inc., and its dictionaries trace their origins to Noah Webster's 1828 dictionary, which the company acquired in 1843. The tool provides authoritative definitions, etymological information, and linguistic data for English words, serving users from students to scholars. It addresses the need for reliable, standardized language resources by offering structured access to vocabulary, pronunciation guides, and historical usage patterns. Its open-source nature allows for community contributions and adaptability, though its primary function remains as a reference tool for English language study and research.

Its dictionaries are widely used by students, writers, educators, and researchers to verify word meanings, origins, and proper usage.

Merriam-Webster's dictionaries offer detailed entries including definitions, pronunciation guides, part-of-speech tags, and example sentences.
