Let's say I want to write N^{eT}, but have N^e as a predefined command \Ne. Thus, I want to append the character T to the superscript of \Ne. Is this possible?

(Note that I don't want to write {\Ne}^T, since that will result in the T being one level above the e. This was adressed in Trick LaTeX into doing double superscripts by the way)

    It may help to explain how you intend to use the macro. Something along the lines of \def\Ne#1{$N^{e#1}$} is acceptable in your case? (usage: \Ne T)

    What about using $\Ne{}^T$ (maybe putting it into a box to prevent a break between e and T)?

  • Haha, I actually didn't know that was possible, Stephen. Thanks!

Or what about an empty optional argument?


Which you can use

$\Ne$ or $\Ne[T]$

  • By the way, what does the asterisk after "\newcommand" do?

    @andreasdr: The starred variant of \newcommand removes the capability to include lengthy arguments (like paragraphs). Surely, since your superscripts will only contain characters (not paragraphs), using \newcommand* is appropriate.

Here is a "clever hack" inspired by (read: shamelessly copied from) the definition of math prime:



\Ne^T \Ne^T_5

You can do \Ne^{}_{} but not \Ne_{}^{}, otherwise the positioning is exactly as N^{}_{}


I would define \Ne in the following way:


This ensures that any following superscripts start at the same height as regular superscripts to N, but also trick TeX in thinking that it's not doubling a superscript:

enter image description here

\Ne\ $\Ne^T$\ $N^{eT}$

Note that this will not work properly for subscripts, since the placement will be off. It would require more effort to make that work.
