What is the subject and verb: Until I have my first cup of coffee in the morning,I am so lethargic I can barely move.

This is the independent clause:

I am so lethargic

What do you think the verb is?

Right.

I assume you don't need to find the verbs in the two dependent clauses.

In the sentence, "Until I have my first cup of coffee in the morning, I am so lethargic I can barely move," the subject is "I" and the verb is "am."

To identify the subject and verb in a sentence, you can follow these steps:

1. Find the main action in the sentence. In this case, it is the state of being described with "am."

2. Ask yourself who or what is performing the action. In this sentence, it is "I."

Therefore, "I" is the subject, and "am" is the verb.
