What role does a participle play in a sentence?

A participle plays a crucial role in a sentence by providing additional information about a noun. Participles are verb forms that can act as adjectives. When used in this way, they help to describe or modify nouns, giving more context or detail. For example, in the phrase "the running water," the participle "running" describes the noun "water" by indicating its state or action. This adds depth to the sentence by conveying not just a noun's identity but also its characteristics or actions associated with it. In contrast, the other options do not accurately reflect the function of participles in sentence structure. A participle cannot act as a conjunction or indicate the main action of a sentence, as those roles are reserved for different grammatical components. Additionally, while participles can appear in questions, their primary role is not to help form questions.
