Who am I

 Find me! I start with ‘P’ and end with ‘E’, but I have thousands of letters. Who am I.

I have all the knowledge you have. But I am small as your fist that your hands can hold me. Who am i.

I am the biggest alphabet, as I contain the most water in the world. Who am I.

Find me who am i. I am the building with number of stories.

Everyone in the world break me when they speak every time. Who am i.
