"These" is a demonstrative pronoun used to refer to specific items or people that are nearby or have been previously mentioned. It helps to indicate a particular group or set of things, distinguishing them from others. For example, in the sentence "These apples are fresh," the word "these" specifies which apples are being discussed. In grammar, "these" is the plural form of "this," which is used for singular items. It is commonly used in everyday language to point out multiple objects, such as books, toys, or friends. Understanding how to use "these" correctly can enhance clarity in communication.
