如何在单词底部写索引？

Question

我想在单词底部写索引

Word(min a element b)

我想将“min a element b”精确地放在“Word”的底部，我不知道该怎么做，我会尝试Word$_{min a element b}$，但它不能满足我的意图。任何帮助表示感谢

Answer 1

如果它是一个具体的词并且amsmath可以使用，解决方案很简单：

\documentclass{article}

\usepackage{amsmath}
\begin{document}

\def\Word{\operatorname{Word}\limits}

\[
\Word_{\textrm{min a element b}}\limits
\]

or $\Word_{\textrm{min a element b}}\limits$


\end{document}

Answer 2

这是另一种选择。

\documentclass[11pt]{article}
\usepackage[usestackEOL]{stackengine}
\begin{document}
This is a \stackunder[1pt]{Word}{\scriptsize min a element b} in text.

And in math wit a deep underset:
\[
y = A + \stackunder[5pt]{Word}{\scriptsize min a element b}
\]
and in math using width of base word (ignoring underset width):
\[\def\useanchorwidth{T}
y = A + \stackunder{Word}{\scriptsize underset}
\]
Then there is this, a left-aligned, multi-line understack:
\[
\stackunder{Word}{\scriptsize\Longstack[l]{Four score\\ and seven\\ years ago}} = mx + b
\]
\end{document}
