The word "its" is a possessive pronoun used to indicate ownership or association. It is commonly used to refer to something that belongs to or is related to a non-human subject, such as an animal, object, or concept. For example, in the sentence "The dog wagged its tail," the word "its" shows that the tail belongs to the dog. Unlike "it's," which is a contraction for "it is" or "it has," "its" does not contain an apostrophe. This distinction is important in writing to avoid confusion. Understanding the correct usage of "its" helps in clear communication, especially in contexts involving animals, objects, or ideas.
