Linguistic metrics are quantitative measures used to analyze language and its structure. They help researchers and linguists assess various aspects of language, such as syntax, semantics, and phonetics. By applying these metrics, one can evaluate the complexity, readability, and style of written or spoken language. These metrics can include measures like word frequency, sentence length, and syllable count. They are often used in fields such as computational linguistics, natural language processing, and literary analysis to gain insights into language patterns and improve communication technologies.
