What is the Clause Structure of 'I Know That'? | Grammar Explained

'I know that...' is a complex sentence containing a main clause and a dependent clause. The word 'that' introduces the dependent clause, which serves as the object of the main verb 'know'. This dependent clause is called an object clause, and it provides information about the object of the action in the main clause. Here's a breakdown:

• Main clause: 'I know' - This part of the sentence contains the subject ('I') and the verb ('know').
• Dependent clause: 'that...' - This clause is introduced by the conjunction 'that' and functions as the object of the main verb 'know'.

The object clause in 'I know that...' clarifies what is being known. For example, in the sentence 'I know that the sun rises in the east', the object clause 'that the sun rises in the east' tells us what the speaker knows. This object clause is essential to the meaning of the sentence and provides a specific piece of information that is being acknowledged by the speaker.
