I am a seven-letter word but if you remove four of my letters I will have one left. What word am I?

I can sizzle like bacon,
I am made with an egg,
I have plenty of backbone, but lack a good leg,
I peel layers like onions, but still remain whole,
I can be long, like a flagpole, yet fit in a hole.

I have a big mouth and I am also quite loud! I am NOT a gossip but I do get involved with everyone's dirty business.

I make two people out of one. What am I?

What Word am I Looking For ?

What you cannot hold but it is yours?

When I go in I might cause pain. I cause you to spit and ask you not to swallow. I can fill your hole. What am I?

Twice ten are six of us,

Six are but three of us,

Nine are but four of us;

What can we possibly be?

Would you know more of us?

Twelve are but six of us,

Five are but four, do you see?

What are we?

I am white when I am dirty, and black when I am clean. What am I?
