The X is always considered to be a letter, but it's more. It is a number in Roman arithmatic. It's a multiplication sign in our arithmatic. It represents a whole word like in xoxox at the bottom of a letter, and sometimes it is as good as a signature.
It also represents an instrument of execution like the Saint Andrew cross.
It can also be a decoration or an ornament in one of our domestic utensils.
