Words have power.
We all know this.

Verbs have power
because without verbs
we can neither laugh nor cry,
neither run nor walk;
we cannot breathe,
nor even be,
without a verb.
A noun too has power
because with it we have, in a sense,
mastery of the object, the person, or the feeling
that we name.
Even an adjective has power,
for it qualifies the noun,
fleshes it out,
makes it more our possession.
A conjunction,
small, insignificant,
you might think
without power,
but ....

All words have power.
We know this,
or we would not be writing poetry.
