Lexical similarity

Lexical similarity refers to the degree of resemblance between the vocabulary of different languages or dialects. It measures how many words share common roots, forms, or cognates. For example, Spanish and Italian have high lexical similarity because they share a lot of similar-sounding words and meanings, stemming from their common Latin origin. This similarity can help speakers of one language understand another with less effort. Lexical similarity is important in fields like linguistics, language learning, and historical language studies, as it provides insights into relationships between languages and their evolution.
