What is the main feature of the indicative mood?

The indicative mood is primarily used to state facts or ask questions about reality. It is the mood that conveys information straightforwardly, presenting statements that can be confirmed or denied. For example, in the sentence "The sky is blue," the indicative mood communicates a factual statement. Similarly, if someone asks, "Is it raining?" they are using the indicative mood to seek factual information. This clarity and directness in conveying information is what distinguishes the indicative mood from other moods that serve different purposes, such as the imperative for commands or the subjunctive for wishes or hypothetical situations. Understanding this function of the indicative mood is crucial in effectively utilizing it in various writing and speaking contexts.
