I see that heart is kè, Is there a different way or word to express heart as in an emotion, like as in "with all my heart"..."or you are my heart" ?

"kè" is generally used for "heart" in that sense.

Pa egzanp:

1. I love you with all my heart.
    Mwen renmen w ak tout kè mwen.

2. You are my heart.
     Ou se kè mwen.

3. You are my heart's desire.
     Ou se dezi kè mwen.

4. It's in the heart of the city.
    Li nan kè (or sant) vil la.
