"Those" is a demonstrative pronoun used to refer to specific items or people that are farther away in distance or time. It helps to indicate a particular group or set of things, distinguishing them from others. For example, in a sentence like "Those apples are ripe," the word "those" specifies which apples are being discussed. In grammar, "those" can also function as a determiner, often used with plural nouns. It is commonly used in everyday language to point out items in a conversation. For instance, "I prefer those shoes over there" highlights a specific pair of shoes, making it clear which ones are being referred to.
