How do I use an English word as a subscript?

To use an English word as a subscript put it in roman font. Do not use math italic.

    \p_{actual}

use
    \p_{\rm actual}


If the word occurs a lot I'll define a command,for example,

    \newcommand{\actual}{{\rm actual}}

so I only need to type
    p_\actual

Remember to put a space after "actual" if it is immediately followed by a letter so LaTeX knows where the end of the command name is.

Here is a complete test file showing how the size of "out" varies depending what size it should be.

    \documentclass[ece]{puthesis}
\newcommand{\out}{{\rm out}}
\begin{document}
$$a^\out + b^{c^\out} + d_\out + e_{f_\out} = g\out$$
\end{document}

The subsubscript and supersuperscript are for illustrative purposes only. Avoid using them unless it is standard practice in yoour disclipline.
