Rheumatic

It is correct to say he/she is an asthmatic.

If a person is suffering from rheumaitsm, is it correct to say he/she is rheumatic?                            

Thanks Marius
Certain things you taught me are engraved in my memory. You are very good at English grammar.

I have two more questions.

1) It is correct to say he/she is an asthmatic.

2)If a person is suffering from rheumaitsm, is it correct to say he/she is rheumatic?                            
Is it incorrect to say he/she is a asthmatic?

I have put a question mark at the end of the second sentence.
Should it be a question mark or fullstop?
The second sentence is not a direct question.

You didn't interrupt anybody here. Everybody is free to reply.
So the question mark is necessary.

You want me to look at the clauses of the sentence.

If a person is suffering from rheumaitsm  --> The subordinate clause

is it correct to say he/she is rheumatic?    --> The main clause
[ I hope I am correct.]

3. When you get your salary, will you buy a new hard drive?
4. When you get your salary, will you buy a new hard drive.
      [ So the fourth sentence is incorrect.]
Please tell me if I am wrong.

Dear Rotter,  

First let me make you an explanation. A clause is a question, statement or command. So, a clause which can stand by itself is called "main clause." In your example, the main clause should be the group of words which ask the question.   

Is it correct to say he/she is rheumatic?    Here, "Is it correct to say" asks the question. The other thing, I mean, "he/she is rheumatic is a subordinate clause which explains the main clause. To decide whether you should use question mark or not, 1- find the main clause 2- identy the subordinate clause or clause, just to make sure 3- put your question mark.  

Here is another example for you:  Do you really see me ₁ , even though I am hiding ₂? As you see, number 1 aks the question but number 2 doesn't have such function. Number one is a main clause so you should put a question mark at the end of the sentence. 

Why did you leave the room?   This is a main clause itself. It asks the question directly.As you see, nothing modifies it.

Doll
Thanks for taking time to reply me again.

I am a bit confused by your explanation about main clauses and subordinate clauses.

I know very well a main clause is a clause which can stands itself as a meaningful sentence.

You wrote the following:
  Is it correct to say he/she is rheumatic?    Here, "Is it correct to say" asks the question. The other thing, I mean, "he/she is rheumatic is a subordinate clause which explains the main clause.

He is rheumatic  OR She is rheumatic are complete sentences thus they can stand itself as complete meaningful sentences. So they are main clauses.

The words ' is it correct to say '  do not make sense; thus they can't stand as a meaningul sentence. So the words ' is it correct to say ' are subordinate clause.

Let us take another simple example:

If I have the money, I will buy a new car.

The words ' I will buy a new car ' is the main clause here because those words together make a meaningful sentence and they can stand itself.

If I have the money  ...  [ These words do not make a sensible sentence; so this is the subordinate clause.]
Please correct me if my understanding is wrong.


Let us take another example:
1. I trained 90 minutes yesterday.
2. I trained yesterday.
   [ I am training at a gym 3 times a week.]
My first and second  sentences are meaningful ones.

3. When I trained yesterday, I talked to a girl who works as a neurosurgeon.
     [ I know her very well. She comes direct from the theatre to train. We often
       talk about cancer aspects because she removes brain tumour.]

In the third example, the words 'When I trained yesterday'  do not make a complete thought. So it is the subordinate clause.

The words ' I talked to a girl who works as a neurosurgeon' are the main clause.

Please correct me if my understanding is wrong.
