# How to pronounce $\mathcal{E}$?

How to say $\mathcal{E}$ when we are speaking about mathematics? Can I call it "curly E"?

And also how to pronounce $\mathcal{A}$ and $\mathcal{B}$ and $\mathcal{P}$ and so on?

It depends on your audience and the context. In physics, $\mathcal E$ usually denotes emf, so you would say that. In set theory, $\mathcal P$ usually denotes a power set, so you would say that. Otherwise, just do your best to describe it in a manner that your audience would understand. “Curly” or “calligraphic” works fine in my opinion.
Side note: You actually can type $\mathcal E$ into Google if you use the Unicode character ℰ (U+2130).
