I'm looking for a word,
A word I've never heard,
A word that describes warm,
A word that can transform,
To mean,
The fuzziness inside that causes the heart to bend,
When someone great calls you a friend.
A word with a strange odd feel,
A word that seems so unreal,
A word that feels like the colour blue in the sky,
A word that feels like the wind that falls off a butterfly,
A word that is so subtle yet so life altering,
A word that describes how the bird's sing.

What is that word?
