Hear me, all ye who enter here,
That you might know my name so dear.
What lies beyond is for few to see,
For just one name shall permit thee.

I am a sound oft spake,
And thine letters are but four.
A helpful sound though I may be,
I've no real meaning more.

For those who speak me, few,
The meaning is all too clear.
But to those who speak me not,
They find me rather queer.
