A modern dictionary is descriptive, meaning it records how language is actually used rather than dictating how people ought to speak. An update can introduce a new headword, attach an additional sense to an established word, or revise an existing definition to improve accuracy. Entries also supply usage labels such as informal, formal, or regional. These labels provide stylistic guidance so readers know where a term fits comfortably.
