Question

What is the differense, between "I am not" and "I don't"?a little offtop:I know and I do know, - is this same? I have written, that people use "do" for make a statements more emphatic.If I say: " I do know", this will be same, if I say" I know"?Kind Regards

"I am not" has something further implied, which may be anything that can grammatically follow "I am (not)". For example, it could mean:

I am not a magician.
I am not hungry.
I am not lying.

"I do not" also has something further implied, which may be anything that can grammatically follow "I do (not)", i.e. a verb. For example, it may mean:

I do not like him.
I do not believe you.
etc.

As you say, "I do know" is an emphasised way of saying "I know".

This may help, even though it's about questions. See

DanilIf I say: " I do know", this will be same, if I say" I know"?

Not exactly the same, no. The form with "do" is used to contradict a negative. The "do" is stressed with the voice.

— Sam and Jill don't know Larry.
— Yes, they do. They do know Larry.

They are different in meaning, but you can often say more or less the same thing with them, for example:

I am not hungry.
I don't want to eat anything.

I am not going.
I don't want to go.

I am not afraid.
I don't fear anything.

I am not ready.
I don't have everything ready yet.

I am not the person you want.
I don't fit the identity you want.

The present tense in English is considered to have three forms: the simple present, the present continuous, and the present emphatic, for example, I know, I am knowing, I do know, respectively. The three forms have more or less the same sense, the continuous being "more extended," and the emphatic being more emphatic, than the simple. For example:

I know him. (This is simple.)
I am knowing him. (This is "more continuous" than the simple.)
I do know him. (This is more emphatic than the simple.)

GPYfurther implied,

GPY, thank you very much for explaining, sorry but I am not understand

I don't understand this "furter implied" combination of words.

You wrote: " I do not like him", but why we can't say "I am not like him?

Danil · Answer

CalifJimThe form with "do" is used to contradict a negative.

Dear Sir, can you say this in another way? When you say "contradict a negative" you mean disagree/protest of negative?

CalifJimThis may help, even though it's about questions. See Does or Is

Thank you for this link, this help me a bit. But I have a question. This quote from your link

[Are], [am] and [is ] are used in conjunction with adjectives or action verbs.

How I should say: "I am not vegetarian" or "I don't vegetarian." I think, that is right answer will be "I am not vegeterian"? I don't see any "action verb" in this sentence, and I don't see adjectives? Is "vegetarian" noun or adjective.?
Sorry if I "blunted"

And one more question, about question construction.

for example:

Is she walk ?
Does she walking?

When I am writing "Does" I should not forget about "ing". I can't say: "Does she walk?", because it will be grammatically incorrect. I should say: "Does she walking?"
Am I right?

DanilGPY, thank you very much for explaining, sorry but I am not understand I don't understand this "furter implied" combination of words.

"something further implied" is something extra, which you mean but do not explicitly say, and which is understood from the context. For example, if someone says "You're lying", and you reply "I am not", then it means "I am not lying". The word "lying" is "something further implied".

DanilYou wrote: " I do not like him", but why we can't say "I am not like him?

"I do not like him" means "I dislike him". "I am not like him" means "I am not similar to him". The word "like" works in both sentences, but only because it has a completely different meaning in each. Most words do not work in both sentences. For example, while you can say "I do not believe him", you cannot say "I am not believe him".

Dear GPY, thank you very much for explaining me. I understood a bit.

"I do not like him" means "I dislike him". "I am not like him" means "I am not similar to him". The word "like" works in both sentences,

I think, this is not a very successful example from my side.

GPYwhile you can say "I do not believe him", you cannot say "I am not believe him".

But, can I say: "I am not believing him" ?" Will this be grammatically correct? This will be present continuous, and it will a bit different meaning?
Kind Regards

DanilBut, can I say: "I am not believing him" ?" Will this be grammatically correct? This will be present continuous, and it will a bit different meaning?

"I am not believing him" is formed correctly according to the rules of grammar, but in practice it doesn't sound very natural. This is because the verb "believe", being a stative verb, is rarely used in the continuous tenses. Various other verbs work OK in this structure, For example, "I am not listening to him", "I am not hurting him", etc, etc. The continuous tense (e.g. "I am not hurting him") refers to action ongoing (or in this case not ongoing) at the present time. The simple present tense (e.g. "I do not hurt him") typically refers to habitual activity.

DanilDear Sir, can you say this in another way? When you say "contradict a negative" you mean disagree/protest of negative?

Just look at the example I gave you.

— Sam and Jill don't know Larry. < Someone makes a negative claim. Notice "don't". He's saying "no".
— Yes, they do. They do know Larry. < The other person contradicts it. This person is saying "yes".

Here's another one:

— You won't want this candy because you don't like chocolate. < Negative claim.
— You're wrong! I do like chocolate. < Contradiction of the negative claim.

And another, in the past:

— You didn't bring the documents. You forgot them again! < Negative claim.
— No, I didn't forget. I did bring the documents. Here they are! < Contradiction of the negative claim.
