When -s forms should be used ?

Hi,

Let me begin by asking you this question.

Which is correct?

A. Mary cooks dinner.

B. Mary cook dinner.

If you know, great. If you don't know, I'll tell you. Then we can discusss your original examples.

Hello Clive,

I feel 'Mary cooks dinner' is correct.

But i do not know why it is correct. All that i can say is that i have heard many such type of sentences.

Hi,
Yes.
Now let's look at these two examples. We put 's' on the end of the verbs 'rise' and deal' for the same reason that we put 's' on the end of 'cook' in my example.

1. The Sun rises in the east.

3. This site deals with various topics.

Do you need some more explanation about this? I'm happy to provide it.

If not, we can discuss your e

Hi,

Do you mean I can understand this only by practice ?
I would be glad if you provide some more explanation on this.

Thank you

Hi,
No. You need to understand how to make the simple present tense.
eg
First person singular I cook
Second person singular you cook
Third person singular he/she/it cooks

First person plural we cook
Second person plural you cook
Third person plural they cook

Also, remember that "rise" and "deal" are verbs, while "lot" is a pronoun. "lots" is the same as the less informal "a lot".

Panesh:
Sunrise (one word) is a noun.In your sentence, the word "rise" is a verb, not a noun. Every sentence must have a verb.

English used to be a highly inflected language. Over the centuries, the inflections have been changed or lost. The addition of -s in third person singular, present tense is one of the verb inflections that still remain in the language
Also the ending

Hi,
That's OK. Everybody has to begin at the beginning.

Do you go to an English class? Do you have an English grammar book?
