A definition is a statement that explains the meaning of a word, phrase, or concept. It provides clarity by outlining the essential characteristics or features that distinguish the term from others. Definitions are crucial in communication, as they help ensure that everyone understands the same idea when discussing a topic. In various fields, such as science, mathematics, and literature, definitions serve as foundational elements. For example, in mathematics, a definition might describe a geometric shape, while in literature, it could explain a literary device. Clear definitions enhance comprehension and facilitate effective dialogue among individuals.
