English sentences are no different from sentences in different languages. They are formed by two essential ingredients that seem to be inseparable- though they are not. These elements are the subject and the verb. Let’s focus our attention to the subject right now. What is a subject? Here is my personal definition:
“A subject is a noun, pronoun, noun phrase, noun clause or gerund that usually precedes and governs the main verb”
I know that you may not like my definition because it might be a little technical. Well, let me give you a few examples:
Subject as a Noun
Rosy cooks delicious.
Subject as a Pronoun
She cooks delicious
Subject as a Phrase
The beautiful girl cooks delicious.
Subject as a Clause
The beautiful girl who is reading that book cooks delicious.
Subject as a Gerund
Her cooking is delicious.
In complex sentences, it is always convenient to identify the main verb first so you can identify the subject. A good exercise is to try to express noun subjects in more complex vehicles of expression such as phrases, clauses and gerunds.
Below is a video where we explain a little more about the subject.
