How to add text and symbol to subscript?

[nhanncv]

This is what I expected

I have tried $succ#sub[W(succ#sub['])]$ but this is what I got
. I have to use sub because _ makes the notation incorrect. So what is the way to subscript text with symbols and texts included.

Thanks.

Does this achieve what you are looking for?

$succ#sub[$W([succ'])$]$

The change was to surround everything within sub[] with $$ so that it is interpreted as math. Calling #sub switches from math mode to content mode so you need to switch back to math.

To get the W closer to the initial succ symbol, you can add a 0pt horizontal distance:

$succ#h(0pt)#sub[$W([succ'])$]$

Oh nice. That’s what I’m looking for. Thank you!

Try this(for single use)

$ attach(succ, br: W([succ'])) $

If you’d like all your succ operators to be like that, then you can redefine the text operator:

// It seems that the default succ definition has limits: true
#let succ = math.op(sym.succ, limits: false)

$ succ_(W([succ'])) $

Removing limits is nice. The in-between solution is

#let sub = sub
$succ sub(W([succ'])).$

#let nosp = h(0pt)
$succ nosp sub(W([succ'])).$
