[Pavanhotscan]

Hi,

If somebody explains me then i have to say "Understand" or "Understood"

Can you please send me some examples on what cases we can use "Understand" and "Understood".

"Understand" is the base form and can be the present-tense form, except with "he", "she" and "it" as the subject.

"Understood" is the simple past form and the past participle.

You can find examples in basic grammar books.

Hi,

For the below topic, My question is when we can use "Understand" or "Understand" in conversation , let us take an example if A teaches on some topic to B then B has to reply it like " I Understand" or " I Understood".

Which one is correct ?

Can you give some examples on "Understand" and "Understood" in Conversation.

B would say, "I understand." If he said, "I understood," it would mean that he used to understand but doesn't anymore.
