gerund phrase as a subject

Explanation:

A gerund phrase is a phrase consisting of a gerund and any modifiers or objects associated with it. A gerund is a noun made from a verb root plus ing (a present participle). A whole gerund phrase functions in a sentence just like a noun, and can act as a subject, an object, or a predicate nominative.
