Question

Young children may know more about life than we realize! Which phrase is the complete subject?

Answer 1

The complete subject is the phrase ' Young Children '.

Complete subject is the main noun in the sentence and the other words or phrases are just telling something about the main noun.

Example sentence -

Young children must guided through their raw age.

Here ' Young Children ' has been again used as a complete subject.

Answer 2

The subject here is the children. Subject is the topic of discussion.

For example in this sentence we are talking about the children that they know more about life that we realize.

So the children are what we are talking about and therefore it becomes the subject while the rest of the sentence is the predicate.
