I’m small but sharp, I point the way, Yet I may guide with words I say. Leave me behind when thanks are due, In three short letters, I’m many things, too.

I'm full of fizz, but contain no broth. I wear many colors, yet own no cloth. I sweeten your tongue, but rot your tooth. What am I?

I wander valleys, touch with but one tip, I never walk alone, yet never slip.

In youth I’m green, in death I’m brown You’ll carve me up, a smile or frown I ward off spirits or at least I’m told You’ll light me up and I’ll shine gold

I am used to represent the color, struggles, history and culture of one's nation.
