Blocks

Blocks

What’s a block to you?

Is it a distance that measures street to street in a city?
Or is it a cube of wood used as a toy?
Perhaps a chunk of material, no discernible or particular shape,
Or defense in sport to prevent offense to move.
It could be housing for the incarcerated, a portion of time,
A section of cheese, or lack of writing ideas.
Half an insult, maybe, paired with head?
Part of an engine, working or dead.
Noun, verb, or adjective, the grammarian in me
Asks today what “block” is to thee.
