„Uralic languages“. Britannica. Nuoroda tikrinta 2022-12-13. „Adjectives, demonstrative pronouns, and numerals originally did not show agreement in case and number with the noun, as is still the case in Hungarian—e.g., a négy nagy ház-ban 'in the four large houses.'“
„Uralic languages“. Britannica. Nuoroda tikrinta 2022-12-13. „In Proto-Uralic the copula verb "be" was lacking in simple predicate adjective or noun sentences, although the predicate was probably marked to agree with the subject. The following Hungarian sentences reflect this situation: a ház fehér 'the house [is] white,' a ház-ak fehér-ek 'the houses [are] white.'“
