THE SILENT K

This little poem is about words with a silent K
Starting with this letter and are then thrown away
Knock on the door and then turn the knob 
K you will see is not doing any kind of job 

To aid one's walking or praying you use a knee
Some use a knuckle if things they don't agree
Mum is knitting a jumper made of spots 
Making sure her wool isn't tangled with knots

Will leave you with some knowledge and then go
Make sure your knickers are hidden from show 
That's what the knights did many centuries ago
Did they actually wear any I'd really like to know
