Ineffable: (in-ef-fa-ble) adjective: Defying expression or description. Too sacred to be uttered. The "super" moon last weekend was ineffable. Or would have been, if it hadn't been cloudy.=)
This is one of those old words that you sing in hymns, but tend to not use in many other contexts. And, it is also one of those words that I have found I sing without knowing the meaning. But, now you do. So, if you want to really butter someone up, use ineffable to qualify their eyes, or hair, or character.=) Or otherwise, use ineffable to describe our indescribable God.
Crown Him with many crowns, the Lamb upon His throne,
Hark! How the heavenly anthem drowns, all music but its own.
Awake, my soul, and sing, of Him who died for thee,
And hail Him as thy matchless king, through all eternity.
Crown Him the Lord of years. The Potentate of time.
Creator of the rolling spheres, ineffably sublime.
All, hail, Redeemer, hail! For Thou hast died for me.
Thy praise shall never, never fail throughout eternity.
O Worship the King, All glorious above,
O gratefully sing His power and His love;
Our Shield and Defender, the Ancient of days,
Pavilion'd in splendour, and girded with praise.
O measureless might! Ineffable love!
While angels delight to hymn Thee above,
The humbler creation, though feeble their lays,
With true adoration shall lisp to Thy praise.
Matchless. Only. Ineffable.
Matchless. Only. Ineffable.
