From the text: When people think about mathematics they probably first think of numbers and not words. But mathematics, with its great intellectual curiosity for ideas, studies words from many points of view ‒ doing what it often does, looking for patterns.

Here I will take a brief look at some of the ways mathematics has looked at words in the hope of exploiting the resulting ideas.
