The concept of "usage" refers to the application of a resource to accomplish a particular task, spanning both practical and abstract aspects. Scholars such as Huber Gray Buehler underscored its significance in establishing appropriate linguistic expression, promoting national and respected usage in English writing.
William James examined how common nouns convey unique intentional meanings, while Thomas Frederick Tout emphasized the empirical foundation of general principles through thorough analysis. These viewpoints together illustrate usage as a link between theoretical ideas and real-world application, influencing communication, cognition, and social conventions.
