The established criteria of the kinship between related language families or of the degree of kinship between two languages or within a group are morphological and lexical commonalities. Whereas lexemes are often borrowed, idioms are borrowed only between closely related languages. Grammatical categories can be created corresponding to patterns of neighbouring languages. Phonological borrowings are rare.
