I possess a head

I flaunt a tail

But I don't have mouth or legs

Can you find out who I am?

Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I am double, I am single,
I am black blue and grey,
I am read from both ends,
And the same either way.

I have a head like a cat and feet like a cat, but I am not a cat. What am I?

What is more useful when it is broken?

I am under you when I am whole.
I shift above you if you remove the first letter.
I come all around you if you remove the second as well.

Can you tell me who I am?

One day, John and his friends were playing around. Jacob hit something with a Pin and it popped. John's dad came into the room that very moment, but he wasn't mad. In fact, he was smiling. What did Jacob hit?

I am weightless, but you can see me. Put me in a bucket, and I'll make it lighter. What am I?

I have an eye but still cannot see.

Who am I?

I sleep during the day and fly at night, but I have no feathers to aid my flight. 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?
