In the Hebrew Bible hallelujah is actually a two-word phrase, not one word. The first part, hallelu, is the second-person imperative masculine plural form of the Hebrew verb hallal.  However, “hallelujah” means more than simply “praise Jah” or “praise Yah”, as the word hallel in Hebrew means a joyous praise in song, to boast in God. Hallel could also refer to someone who acts madly or foolishly.

The second part, Yah, is a shortened form of YHWH, the name for the Creator. The name ceased to be pronounced in Second Temple Judaism, by the 3rd century BC due to religious beliefs. The correct pronunciation is not known, however, it is sometimes rendered by Christians as “Yahweh” or “Jehovah“. The Septuagint translates Yah as Kyrios (the LORD), because of the Jewish custom of replacing the sacred name with “Adonai“, meaning “the Lord”.  source: Wikipedia
