HalleluYAH...is Praise to Our Creator's Name

...When you say, "HalleluYah,"  you are actually saying, "Praise Yah."  You are  praising His name.  In the Bible, HalleluYah  is an exclamation of joy and gratitude and has survived the passage of centuries, transcending the barriers of language and culture. What exactly does it mean? According to the Talmud, HalleluYah is the most sublime expression of God’s praise, combining together in one word both praise (hallel) and God’s Name (the two-letter, YH, Name ‘Ya-H’).

Here's some info. I found about the word, "HalleluYah" 
(commonly written as Hallelujah)
Hallelujah, Halleluyah and the Latin form Alleluia are transliterations of the Hebrew word הללויה (Standard Halleluya, Tiberian Halləlûyāh) meaning "PraiseYah" (from the first two letters of the name of God, YHWH, written JHVH in Latin). Hallelujah is found primarily in the book of Psalms. The word is used inJudaism as part of the Hallel prayers, and in Christian prayer. It has been accepted into the English language and has a similar pronunciation in many other languages.
(I have heard that where ever you go, HalleluYah is pronounced just the same way as every where else.  Abba's name preserved throughout the ages.)


The second part, Yah, is a shortened form of YHWH, the name for the Creator.^[3] This name is not pronounced by Jews, as they are not permitted to speak the name of God, and in any case the correct pronunciation is not known. However, it is sometimes rendered by Christians as "Yahweh" or "Jehovah".
