Cognated is a term that refers to the relationship between two or more words that have a similar origin or meaning. Antonyms for cognated include unrelated, dissimilar, unassociated, distinct, divergent, and disparate. These words indicate a lack of similarity, commonality or association between two or more things. For instance, unrelated terms do not share a common ancestry. Dissimilar terms are opposite in nature, while unassociated terms have no connection. Distinct terms are unique and separate from one another, while divergent terms follow different paths. On the other hand, disparate terms are different in nature, kind or quality. By contrast, cognated terms are words that are etymologically related and share a common origin or meaning.
