a letter

The 2nd letter on the left of the 2nd row of the keyboard broken. Amazing how one important letter can make you have to think of a new word to replace any word containing that letter which broke.

I write e.mail with formula  "let X equal letter broken."  One important letter and I am in trouble.

Why did  z or x not break?

Oui, I hit it too hard one time and that broke it. Maybe I can fix it, maybe not. One letter from 26 of them and I have to think about everything I type. Maybe it will be a good thing,maybe not. 

But there it iX !
