Major - subject complements
Explanation
The above word is the complement because “I” is used as the subject in the sentence while “significant" becomes the compliment.
Words that follow a verb are usually regarded as the subject complement. The words are generally linked to verbs.
The subject complement aims to describe and identify a new verb in a sentence.
In simple terms, the subject complement gives more meaning to the subject of the sentence.
A complement therefore can be a pronoun, noun, or even adjective based on the description.
