Question

I understand exactly what_ (mean). use the simple present and simple past forms of verbs.​

Answer 1

Answer::

I understand exactly what you mean. (Simple Present)

I understand exactly what you meant. (Simple Past)

Answer 2

The correct form of sentence in both the tenses is provided below:

1. According to Simple present tense the correct answer in the blank is: you mean.

• The verb form does not change its form in this tense.
• It is always the first form of the verb in this case.
• It is the base verb form and also this sentence is directly spoken to the second person by the first person so "means" is not correct.
• The verb form is the action describing whether it is taking place in the present, has taken place, or will take place.

2. As per simple past tense the correct answer in the blank is: you meant.

• In this form of a tense, the correct verb form changes to "meant".
• It shows that action has already taken place and was completed.

• Hence, the answer is provided.
