I want to write:
and give error: 
When I put
\textit${x_{min}}$ It also error
1 Answer
\textit(x_{min}} is an error as the content of \textit is text mode so can not have _
\textit$x_{min}$ is \textit{$}x_{min}$ with a lone $ as argument to \textit
the usual markup would be $x_{\min}$ or if you really do want min in italics $x_{\mathit{min}}$
If it is not mathematics then \textit{x\textsubscript{min}} is another possibility.

- You probably mean
\textit{x\textsubscript{min}}:-)Zarko– Zarko2020-01-13 20:27:09 +00:00Commented Jan 13, 2020 at 20:27 - @Zarko up, down, what's the difference:-)David Carlisle– David Carlisle2020-01-13 20:39:49 +00:00Commented Jan 13, 2020 at 20:39
- position of
min:-) :-), however in principle there is no difference, so you are right :-)Zarko– Zarko2020-01-13 20:52:24 +00:00Commented Jan 13, 2020 at 20:52 - Maybe a less elegant suggestion but what if you put \ in front of _ given that you want to have it in text?Dario– Dario2020-01-13 22:47:40 +00:00Commented Jan 13, 2020 at 22:47
- @Dario I'm assuming the questioner wants x with a subscript "min" not just text with a literal underscore
x_min???David Carlisle– David Carlisle2020-01-13 22:55:57 +00:00Commented Jan 13, 2020 at 22:55
$x_{min}$should work for the latteritalic. so I added in \textit{x_{min}}$x_{\min}$instead of what you're currently doing. At best, you're need\textit{x\textsubscript{min}}._for a subscript only works in math mode. Hence the error message when you use it in text mode.
