I used to chase and fight at night, Now I nap in warm sunlight. No more babies, no more roar, What was done so I roam no more?

I’m held, not seen, yet often shared, I may be calm or strongly declared. I’m not a fact, though I may sound, I change depending who is around.

Silent guardian of words, resting on a shelf, unlocking a world of meanings, from A to Z it dwells. Need a spelling then come. And read thee

For six days straight, I toiled away. On the seventh, I took a vacay.

With two s's I'm super sweet. With one, I'm just sand.
