Linguistic typology is a subfield of linguistics that studies and classifies the structural diversity of the world's languages. It focuses on identifying and categorizing patterns of similarity and difference in the phonological, morphological, syntactic, and semantic structures of languages. Linguistic typologists aim to uncover universal features shared by all languages, as well as language-specific characteristics that distinguish one language from another. By studying a wide range of languages from different language families and regions, typologists seek to better understand the principles that underlie human language and the ways in which languages can differ from one another.
