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?

Forwards I am heavy. Backwards I am not. What am I?

I can lie, but I cannot speak. People use me to welcome and clean.

Pronounced as one letter, and written with three, two letters there are, and two only of me. I’m double, I’m single, I’m green blue, brown and gray, I’m read from both ends, and the same either way.
