Annym means 'inspiration', 'muse', 'genius', or 'poetic frenzy', ‘a fluid, a flowing', and 'a living principle, a being, a spirit, essential.'
Let me share the words of Taliesin, Ancient Bard …
The Annym I sing,
From the deep I bring it,
A river while it flows,
I know its extent;
I know when it disappears;
I know when it fills;
I know when it overflows;
I know when it shrinks;
I know what base
There is beneath the sea.
Annym, the 'flowing spirit', is a river, drawn from the sea by the poet's singing. The 'sea' could be a reference to the all-encompassing spirit that surrounds us, the 'river' being that portion which we may draw into ourselves or which resides within as our spiritual essence. Annym is ours by drinking from the Cauldron of the Goddess.
Every object in the physical realm holds this spirit or Annym. Every tree, bird, animal, reptile, fish, every blade of grass and every other thing we know or can dream of holds within its own Annym, all part of the greater whole. Annym is not born, and never dies.
