õõsas

ésas is the feminine plural demonstrative pronoun and determiner in Spanish, used to refer to feminine nouns that are not near the speaker. It corresponds to "those" in English. In contemporary standard Spanish the unaccented form "esas" is customary; the accented form "ésas" appears mainly for emphasis or in older or stylistically marked texts. For example: "Ésas llaves son de acero" meaning "Those keys are steel." The accent is a diacritic, not a separate word, and its use is largely optional today.

Orthography and historical use: Spanish has used marked forms like éstas, ése, ésa to distinguish pronouns from determiners when ambiguity could arise. Since orthography reforms in the 21st century, many of these diacritics are considered optional; most writers use the unaccented forms "esas," "estas," etc. The accent in "ésas" thus signals emphasis, rather than a distinct lexical sense, and is more common in stylized writing or older texts.

Lexicography and usage: In dictionaries, "ésas" is described as a variant of the standard "esas" used for emphasis. It is not a proper noun, and there are no widely recognized places or organizations named "ésas." Overall, "ésas" serves primarily as an accented emphasis form within Spanish orthography, with the unaccented "esas" being the prevailing form in everyday writing.
