Babel：在文档中插入额外断点时尊重前言连字符断点

Question

\hyphenation{}除了序言中已用或定义的断点之外，是否可以在单词中插入额外的断点\babelhyphenation{}？在下面的示例中，一旦我使用 添加自定义断点，序言中定义的（缺少）断点就会被完全忽略\babelhyphen{soft}。

\documentclass{article}
\usepackage[british]{babel}
\textwidth=1pt
\parindent=0pt
\hyphenation{incomprehensibility}%or \babelhyphenation{incomprehensibility}
\begin{document}
  xxx incomprehensibility \\% not hyphenated as per preamble

  xxx i\babelhyphen{soft}ncomprehensibility% not hyphenated as i-ncomprehensibility, but as i-ncom-pre-hens-ib-il-ity
\end{document}

Answer 1

类似命令的\babelhyphen{soft}工作方式是插入宽度为零的空格。因此，它们可以有效地将一个单词拆分为两个单词。如果要控制某个部分的连字符，您还必须进行以下设置\hyphenation：

\documentclass{article}
\usepackage[british]{babel}
\textwidth=1pt
\parindent=0pt
\hyphenation{incomprehensibility ncomprehensibility}% both parts \babelhyphenation{incomprehensibility}
\begin{document}
  xxx incomprehensibility \\% not hyphenated as per preamble

  xxx i\babelhyphen{soft}ncomprehensibility% 
\end{document}
