Hallelujah

Helen Shapiro was very taken with the word Hallelujah so this is the meaning:-

Hallelujah, Halleluyah and the Latin form Alleluia are transliterations of the Hebrew word הללויה (Standard Halleluya, Tiberian Halləlûyāh) meaning "Praise Yah" (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 in Judaism 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.
