$A \subseteq B$. I want to write "bounded" below the \subseteq symbol. How can I do it?

I found a way to write text above and below an arrow symbol. But how to do the same with the subset symbol?

    Consider amsmath's \underset. See How to add text under symbol in equation ? – Werner Jan 05 '21 at 07:14
  • You got your answer in Werner's comment, but since the word "bounded" is fairly long, I'd probably try to avoid writing it below \subseteq since it pushes the two sets away from the symbol. Since it will additionally set up your line heights, I would try to avoid even shorter forms like "bdd." in inline math. I would probably just write what you need to say in words. If this is a recurring and important concept you may be able to define a symbol for it. I have seen \Subset used for a compact set contained in another, but there are other similarly-shaped symbols ... – moewe Jan 05 '21 at 08:23
  • ... (see the comprehensive LaTeX symbol list on CTAN: http://mirrors.ctan.org/info/symbols/comprehensive/symbols-a4.pdf) or you roll your own symbol like https://tex.stackexchange.com/q/22371/35864 or https://tex.stackexchange.com/q/147439/35864. – moewe Jan 05 '21 at 08:24

Using the \clap command from mathtools, you can have the default spacing of \subset:

\documentclass{article}
\usepackage{mathtools}

\begin{document}


[
 A \underset{\clap{\scriptsize bounded}}{\subseteq}B ]


\end{document}
