Question

20.

I don't know why he did that. (Identify the type of sentence compound complex



​

Answer 1

Answer:

RHis is because the sentence can be split into two parts: "I don't know", and "why he did it". Since "why he did it" contains the conjunction "why", it is a dependent clause and hence it a complex sentence.

Answer 2

The sentence "I don't know why he did that" is a complex sentence.

The types of the sentence are identified using the conjunction used in the statement. If the conjunction acts as a coordinator then it will be a compound sentence. Similarly, if the conjunction acts as a sub-ordinator it will be a complex sentence.

A compound sentence has two clauses where the first clause is dependent on the second sub-ordinate clause.

• In the above statement, the conjunction 'why' is used to join both the sentences.
• The clauses are "I don't know why" and "He did that", where the first clause I don't know why is totally dependent on the second one.
• Thus, the sentence will be complex in nature.
