Subject Complement:
* A subject complement is a word or phrase that renames or describes the subject of a sentence.
* It typically follows a linking verb like "be," "seem," "become," "appear," etc.
* Examples:
* "The cat is a fluffy Persian." (Persian renames the subject "cat")
* "My favorite hobby is reading." (Reading describes the subject "hobby")
Gerund:
* A gerund is a verb form ending in "-ing" that functions as a noun.
* Examples:
* "Swimming is my favorite exercise." (Swimming acts as the subject of the sentence)
* "I enjoy hiking in the mountains." (Hiking acts as the object of the verb "enjoy")
Combining the concepts:
You can definitely have a gerund as a subject complement. For example:
* "My favorite activity is jogging." (Jogging, the gerund, describes the subject "activity")
Why there is no specific term "subject complement gerund":
The term "subject complement" is already broad enough to encompass different types of phrases, including gerunds. There's no need for a separate term for gerunds specifically acting as subject complements.
In essence, when a gerund acts as a subject complement, it simply renames or describes the subject.
