\'Me\' and \'Ma\' are used to make verbs negative, whereas \'degil\' is used to make adjectives (such as \'iyi\') negative. \'mi\' is the question suffix, which can take other forms because of vowel harmony.

In some cases -mi is going to have a suffix at the end, in the third person use there will not be such use. Please see examples below

Iyi miyim (am I well)
Iyi misin (are you well - singular or informal use)

Iyi mi (is he/she/it well)
Iyi miyiz (are we well) and so on

And also with verb use:
Geliyor muyum (am I coming)
Geliyor musun (are you coming)
Geliyor mu (is he/she coming)

What happens is we can drop the WE in ARE WE COMING, because the suffix attached to -mi will give you WHO is coming.
Example:

Ben geliyorum (I am coming)
Geliyorum (I am coming) Both correct

Biz geliyor muyuz?
Geliyor muyuz? both correct

This is one of the amazing features of Turkish. When you drop the object, I, you, he, she etc, you still get the same meaning because of the suffix at he end of the verb.

In English that doesn't happen.
Am (I) coming?
are (you) coming?

Dear Klaus,

When you have a negation -me -mi -mu etc the suffix for the negation comes right after the root verb, and before the tense suffix... let me give an example

I am NOT going
Git-mi-yor-um
or
Ben git-mi-yor-um

now let's make this a question:
Am I not going?
Git-mi-yor mu-yum?

As you can see the first part of the verb did not change, we added the question suffix and then the object suffix at the end (what is it called personal pronoun suffix?)

Now, "degil" is used for NOT, but not with actual verbs like go, eat, reject, sleep... But with the verb to be....

Am not
are not

Ben iyi degilim
I am not well

Oh just one more note, I thought that for a person to say they are feeling fine, the correct English would be I am well, or are you well, instead of good?
Can someone please answer this one for me?

I thought you can be well, but you can be good AT something.

Or are both used?

Are you good?
Are you well?
Are you fine? (I vote for the last two)

Please a native English speaking person, can you answer this one?

When I used "I am good" in the US, during my trips or stay in Canada, or now here in Australia, a few people corrected me saying instead of "good" I should use "well or fine"

Question:
Geliyor mu-sun?
Geliyor mu-sunuz?

Negation:

Gel- iyorum.
Gel- mi -yorum.
Gel- iyoruz.
Gel- mi -yoruz.

Did you see the difference?
Klaus, if you are asking you put the "mu" etc at the end of the question as a separate word. Do not tie them together please:)

In negation the -mi etc. is put into the word. Verb root, then the -mi, and etc.:)

A summary and additional explanation about suffix "mi" in Turkish:

We have to negotiate 2 different points:
1. "mi/mı/mu/mü" as question suffix:

a. Simple Present Tense (Please see the exceptions) :

Ben gelir miyim? = Do I come? (Suffix “mi” is not at the end of the sentence.)
Sen gelir misin? = Do you come? (Suffix “mi” is not at the end of the sentence.)
O gelir mi? = Does he/she/it come? (Suffix “mi” is at the end of the sentence. This is usual because personal pronoun suffix is not used in the sentence with third single pronoun.)
Biz gelir miyiz? = Do we come? (Suffix “mi” is not at the end of the sentence.)
Siz gelir misiniz? = Do you come? (Suffix “mi” is not at the end of the sentence.)
Onlar gelirler mi? = Do they come? (Suffix “mi” is at the end of the sentence.This is exception.)


b. Simple Past Tense (There is not any exception. Suffix “mi” is at the end of the sentence.)

Ben geldim mi? = Did I come? (Suffix “mi” is at the end of the sentence.)
Sen geldin mi? = Did you come? (Suffix “mi” is at the end of the sentence.)
O geldi mi? = Did he/she/it come? (Suffix “mi” is at the end of the sentence.)
Biz geldik mi? = Did we come? (Suffix “mi” is at the end of the sentence.)
Siz geldiniz mi? = Did you come? (Suffix “mi” is at the end of the sentence.)
Onlar geldiler mi? = Did they come? (Suffix “mi” is at the end of the sentence.)


c. Present Continuous Tense (Please see exceptions) :

Ben geliyor muyum? = Am I coming?
Sen geliyor musun? = Are you coming?
O geliyor mu? = Is he/she/it coming? (This is usual because personal pronoun suffix is not used in the sentence with third single pronoun.)
Biz geliyor muyuz? = Are we coming?
Siz geliyor musunuz? = Are you coming?
Onlar geliyorlar mı? = Are they coming? (This is exception. Because question suffix “mi” is at the end of the sentence.)


d. Future Tense (Please see exceptions):

Ben gelecek miyim? = Will I come? (Suffix “mi” is not at the end of the sentence.)
Sen gelecek misin? = Will you come? (Suffix “mi” is not at the end of the sentence.)
O gelecek mi? = Will he/she/it come? (Suffix “mi” is at the end of the sentence. This is usual because personal pronoun suffix is not used in the sentence with third single pronoun.)
Biz gelecek miyiz? = Will we come? (Suffix “mi” is not at the end of the sentence.)
Siz gelecek misiniz? = Will you come? (Suffix “mi” is not at the end of the sentence.)
Onlar gelecekler mi? = Will they come? (Suffix “mi” is at the end of the sentence.This is exception.)


2. “mi” is also used in some negative sentences. However its mean is quite different. (mi=NOT)
For example:
Ben gel-mi-yorum.
