I have three letters.

I read the same forward and backwards.
I know you’ll get the answer, I know you’ll see.
It’s a word that is important to you and me.
There is a mountain between a pair of me !

What word am I?

I’m a 6 letter word

I can kill people
People can also travel on me
1,2,3,4 an animal
3,2,1,5 helps reducing friction

Who am I?

Rich Man keeps me in pocket,

Poor Man throws me away,
Kids eat me,

I’m not an English word.
__U__E__L

Who am I?

I am everywhere.
I am inside you.
I surround you.
I can be seen by you.
I can kill you.
Yet you play in me.

What am I?
