S

The illustrated alphabet Part 19: S is for STAPLE.

A staple is a U-shaped fastener made of metal but bendable and dependable.

a: a metal loop both ends of which are driven into a surface to hold the hook, hasp, or bolt of a lock, secure a rope, or fix a wire in place

b: a small wire both ends of which are driven through layers of thin and easily penetrable material (such as paper) and usually clinched to hold the layers together
c: a usually metal surgical fastener used to hold layers of tissue together (as in the closure of an incision).

Never forget, Winston Churchill had a staple diet and so should you.
