Pronunciation of variable with subindex

Question

This question is about pronunciation of variables with a subindex such as $P_i$.

In this Stanford video lecture on statistical mechanics $P_i$ is pronounced " Pees of i" and $E_i$ is pronounced "Ees of i". Is this pronunciation standard in the US? In Europe I have just heard "Pee i" and "E i".

The lecturer is likely saying "P sub i" with "sub" being short for subscript. — carmichael561, Mar 31 '17 at 00:06
Yes, Susskind is definitely saying "$P$ sub $i$" and that's standard in the US. For superscripts, it would be "$P$ super $i$." — Fabio Somenzi, Mar 31 '17 at 00:25

Most of my lecturers say "P of i" and that's how I say it as well. But I've heard "P sub i" many times.
