Madanm, In "bye a, diven an e wiski la" do you eventually know which article to use by sound, or is it by rules of grammer only? I guess what I am saying is, do you just learn which article to use when you learn a particular word? So far I have not had much difficulty in memorizing which article to use when I learn a certain word. Mesi Madanm.

The Haitian Creole grammar makes it easier to know which def. article to use.
It says to go by the -ending of the words...

P.S.  the word "wiski" will take another vowel, not "la".  After reviewing the following rules, would you like to figure out which def article goes after "wiski"?

After a vowel (vwayèl bouch) (a, e, è, i, o, ò), we use "a":
examples:
kò a
matla a
mont Kendra a

after a consonant (t, y, l, d, etc....), we use "la"
examples:
pitit la
kay la
mayo Pòl la

After an "m" or "n" sound (machin, fanm, kazèn) we use "nan" - sometimes people use "lan"
examples:
madanm nan
mwa desanm nan
chemiz Edison lan

After a nasal vowel sound (an, on, en), we use "an"
examples:
pen an
pon an
Sa se òdinatè mwen an.

After a consonant which follows a nasal sound/vowel (vwayèl nen), we use "lan"
examples
mant lan
monnonk lan
matant lan

and then you will use the nasal "an" or "lan" if the word sounds nasal, no matter what the ending is:
examples:
zanmi an
fanmi an
lanmou an
Ban'm pitit la or Ban'm pitit lan.

Why didn't you go?

other examples:

2.

Why are you so happy?

3.

Could you please explain ADEKE and use in a sentence?

Do you mean "adekè"?

    If you're helping out and you have regret about it, it's better that you don't help me at all.

"From" continues to confuse me...I found a Jan 2013 post where you used 'moun' as 'from.' Is this the same as 'soti'? Mesi.

You can use 'MOUN" when indicating origin such as
Mwen se moun New york
I am a person of New York (literally)
I am from New York.

Li se moun Alabama.
She is from Alabama.

So yes,  it means the same as "Mwen soti New York" or "Mwen soti Alabama"

If you haven't done so already, check this link: Using FROM in Creole
And I have also used "moun" in the audio post titled Nan Estasyon Bis la

Can you explain the rules for the mwen to m' contraction?

"MWEN" can be used as personal pronoun: I or ME
"MWEN" can be replaced with contraction "m".
example:
1. Mwen te wè li.
    or 
   M te wè li.
   I saw it.

2. Rele mwen lè w rive.
    or
    Rele m lè w rive.
    Call me when you arrive.

"MWEN" can be used as possessives: MY, MINE (singular or plural)
example
3. pitit mwen - my child
4. pitit mwen yo - my children
Do not use contraction after a word that end with a consonant.
The word "pitit" ends with "t" which is a consonant.  So you cannot say "pitit m".  You will always say "pitit mwen".

5. pye mwen or pye m - my foot
The word "pye" ends with a vowel "e" which is a vowel, so you can say "pye mwen" or "pye m"

6. kesyon mwen or kesyon m - my question
The word "kesyon" ends with a nasal vowel "on", so you can say "kesyon mwen" or "kesyon m"

Sometimes a definite article may come after MWEN:
7. kesyon mwen an or kesyon m nan. - my question
8. kesyon mwen yo or kesyon m yo - my questions

We do not use contractions after these prepositions POU, NAN, SOU at the end of a sentence:

9. Malèt la tonbe sou mwen.
   You cannot say
   Malèt la tonbe sou m.

10. Fè sa pou mwen tanpri.
      you cannot say
     Fè sa pou m tanpri

11. Lespri Bondye te desann sou mwen
     you cannot say
     Lespri Bondye te desann sou m.
