Answer:
I scribble forms of the finest letter, And repel elements of the harshest weather. I am an arrow-aimer and a dust-breaker.
A mile from end to end, yet as close to as a friend. A precious commodity, freely given. Seen on the dead and on the living. Found on the rich, poor, short and tall, but shared among children most of all.
A hill full, a hole full; yet you cannot catch a bowl full. What is it?
Voiceless it cries, wingless flutters, toothless bites, mouthless mutters.
Twigs and spheres and poles and plates. Join and bind to reason make.
If it’s information you seek, come and see me. If it’s pairs of letters you need, I have consecutively three. What am I?
