We are presented with a document discussing English grammar concepts including main and subordinate clauses. It provides examples of how two sentences can be joined using a relative pronoun like "who" or "that" when they share a common item. Relative pronouns substitute this common item and link the clauses together while making the subordinate clause's meaning reliant on the main clause for completeness.

1. Mrs. Anabel Montes - English teacher

2. We are waiting for Apu.
Apu is from India.
Same thing in different sentences.
D.O.
Subj
.

3. We are waiting for Apu,
Apu is from India.

4. We are waiting for Apu , is fromIndia.who
This is the main clause. This is the subordinate clause.
The two sentences can be linked
into one.
We use a relative pronoun to
substitute the common item and
join the two sentences in one.

5. Main /independent clause
If we remove the subordinate clause
from the sentence, its meaning is still
complete.
Subordinate/Dependent clause
Its meaning is incomplete if we remove the
main clause.
