The term "indicative" refers to a grammatical mood used to make factual statements or ask questions. It is the most common mood in many languages, including English, and is used to express reality or certainty. For example, in the sentence "She walks to school," the verb "walks" is in the indicative mood, indicating a straightforward action. In addition to grammar, "indicative" can also describe something that serves as a sign or indication of a particular condition or situation. For instance, a rising temperature can be indicative of climate change, suggesting a trend that may require further investigation.
