Language universals are features or characteristics that are common to all human languages. These can include aspects like grammar, vocabulary, and phonetics. For example, most languages have nouns and verbs, which are essential for constructing sentences. These shared traits suggest that all human languages are shaped by similar cognitive processes. There are two main types of language universals: absolute and statistical. Absolute universals apply to all languages without exception, while statistical universals are more common but may have exceptions. Understanding these universals helps linguists study the nature of language and its role in human communication, contributing to fields like linguistics and cognitive science.
