2+4 Agreement

The 2+4 Agreement refers to a linguistic rule in Spanish grammar where the number "2" always takes a plural form when accompanied by a "4" or any other plural quantity. Essentially, if you're talking about two items, the associated adjectives or nouns should also be plural to match. For example, "dos libros" (two books) correctly uses the plural "libros." This agreement ensures clarity and grammatical consistency between numbers and the words they modify, helping the sentence sound natural and correct to native speakers.
