If I’m in your mouth, you have improved it, but if I’m top of mind, you get a title.

You take a seat without a glance, assuming I’ll support your stance. I do my job, I take the hit, until I don’t. . . Well, enjoy that sit!

I'm cracked but never broken, Each word a woven thread, My meaning lies unspoken Until my clues are read. You're reading me, and even so, I am the thing you seek to know.

I have keys but no locks, I have space but no room, You can enter, but you can’t go outside. What am I?

I have two long teeth but no mouth to speak, I move heavy loads all days of the week. What am I, that helps to stack crates to the highest peak?
