我通常使用预定义的环境定义来编写定义，例如：
\begin{definition}[THE WORD]
...
\end{definition}
我想要两件事：首先，单词定义用黑色下划线（与单词颜色相同）；其次，之后出现的单词（[] 中的单词）用红色书写。
之后直接写入元素的定义，是否可以将其放在一行中？然后只
" definition (the word).
blablabla..."
如果最终我可以在不改变代码的情况下完成所有这些更改（仅在代码开头应用修改，并保持样式\begin{definition}[THE WORD]），那就太棒了
我的文档的选项是：
这是一本书，我准备给你发一张图片，我使用的包装有很多……我认为只有盒子里的那个让你感兴趣：
\usepackage{lmodern}
\usepackage[most]{tcolorbox}
\usepackage{fancybox}
但是是的，我使用了所有其他经典的软件包，例如 tikz 或数学内容软件包。

您可以创建自己的定理风格，但请重新考虑使用下划线，还有许多其他（好的）方法来强调文本。
\documentclass{book}
\usepackage{xcolor}
\usepackage{amsthm}
\newtheoremstyle{Marine}% name
{3pt}% Space above
{3pt}% Space below
{}% Body font
{}% Indent amount
{}% Theorem head font
{:}% Punctuation after theorem head
{\newline}% Space after theorem head
{\underline{\thmname{#1}\thmnumber{ #2}}\thmnote{ \textcolor{red}{ (#3)}}}% Theorem head spec (can be left empty, meaning ‘normal’)
\theoremstyle{Marine}
