if i say that is a valid point. is valid point as a whole subject complememnt or only point

In the phrase "that is a valid point," the complete noun phrase "a valid point" serves as the subject complement.

Breakdown:

1. Subject: "that"
2. Verb: "is"
3. Subject Complement: "a valid point"

Explanation:

• The subject complement renames or describes the subject. In this case, "a valid point" describes what "that" is, making the entire phrase the subject complement.
• Therefore, "valid point" is part of the subject complement, but when considering the grammatical function of the phrase, it is more accurate to say that "a valid point" acts as the subject complement as a whole.

In summary, "a valid point" is the complete subject complement, while "point" is only a part of that complement.
