Suyos

Suyos is the plural form of the Spanish possessive pronoun suyo and is used to refer to possessions belonging to someone previously mentioned or understood. In modern usage, the form agrees with the possessor in gender and number, not with the thing possessed. The standard possessive determiners before a noun are su and sus, but suyos (and its related forms) appear when the noun is omitted or when the possessor is being stressed or clarified.

The full set of forms is suyo (masculine singular), suya (feminine singular), suyos (masculine or mixed plural), and suyas (feminine plural). These can function as independent pronouns or as pronominal adjectives in phrases such as el suyo, la suya, los suyos, or las suyas. For example, Los libros son suyos means “The books are theirs/his/hers,” depending on context; La casa es suya means “The house is hers/his.”

In everyday Spanish, the ordinary way to express possession is with the possessive determiner su or sus before the noun (su coche, sus ideas). Suyos is more common when the speaker wants to refer to the owner’s possessions without repeating the noun, or to avoid ambiguity about which person is being referenced. The forms suyos and susyas function similarly when used as pronouns to stand in for a previously mentioned noun phrase.

Etymology traces suyo back to Latin suus, meaning “his/her/its/their own.” While suyos is primarily a grammatical feature of Spanish, it also appears in literature and formal writing to achieve emphasis or clarity about ownership.
