Genus
Grammatical gender in Spanish affects several types of words (and their mutual agreement) which have inflection in the Spanish language according to grammatical gender: nouns, adjectives, determiners, and pronouns. All Spanish nouns have lexical gender, either masculine or feminine, and most nouns referring to male humans or animals are grammatically masculine, while most referring to females are feminine. In terms of markedness, the masculine is unmarked and the feminine is marked in Spanish.
