Chaff (/ˈtʃæf/ or /ˈtʃɑːf/) is the dry, scaly protective casings of the seeds of cereal grain, or similar fine, dry, scaly plant material such as scaly parts of flowers, or finely chopped straw. Chaff is indigestible by humans, but livestock can eat it and in agriculture it is used as livestock fodder, or is a waste material ploughed into the soil or burnt.
"Chaff" comes from Middle English chaf, from Old English ceaf, related to Old High German cheva, "husk".
In grasses (including cereals such as rice, barley, oats and wheat), the ripe seed is surrounded by thin, dry, scaly bracts (called glumes, lemmas and paleas), forming a dry husk (or hull) around the grain. Once it is removed it is often referred to as chaff.
In wild cereals and in the primitive domesticated einkorn,emmer and spelt wheats, the husks enclose each seed tightly. Before the grain can be used, the husks must be removed.
The process of loosening the chaff from the grain so as to remove it is called threshing – traditionally done by milling or pounding. Separating remaining loose chaff from the grain is called winnowing – traditionally done by repeatedly tossing the grain up into a light wind which gradually blows the lighter chaff away. This method typically utilizes a broad, plate-shaped basket or similar receptacle to hold and collect the winnowed grain as it falls back down.
A child was born into this world
With great emotion he was loved
The evil seed slept in his body
Spreading it's roots before the glory
The hell was risen when he was twelve
The squeeze of the trigger was a move he did well
So he killed his parents killed his friends
With black spirit he filled himself
Soon he was taken in custody
But the inner seed was so well-rooted
He needed more the evil doer
[Chorus:]
With terminal intensity operation was made
His ties were broken and the doors opened
With terminal intensity and hardened heart
Now walking among us a voice in his head
He has an agenda a secret mission
Taking orders from higher levels
Fighting a battle for you and me
So we can live in our world of dreams
Tottering on the edge of the grave
Facing violence every day
Causes the new set of priorities
Kills with a pleasure every day
And the hindbrain behind will be safe
From the extra people to play his game
Wrapping himself up in mystery
[Chorus:]
With terminal intensity the plan was made
But there is no control in evils way
With terminal intensity all hell´s breaking loose
No-one can control how evil moves
Unestrained anger deep inside
Turns himself against the person of high
But will be killed in the name of law
