Learn Spanish (Latin America): Esos abrigos están ahí.

The singular word for "that" (masculine) is ese, but its plural form for "those" is esos, not eses. Since abrigos (coats) is a masculine plural noun, we use esos.

Why do we use están instead of son here?

Both verbs mean "are", but we use están (from the verb estar) when talking about physical location. Since the sentence is about where the coats are (ahí), we must use estar.

Is there a connection between using esos and ahí?

Yes! They both represent a "medium distance." Esos means "those" (items not right here, but not too far away), and ahí means "there" (at that same medium distance). They naturally pair together.

Why does están have an accent mark over the 'a'?

In Spanish, words ending in 'n' usually emphasize the second-to-last syllable. The accent mark in están breaks that rule, telling you to put the spoken stress on the final syllable instead: es-TAN.
