=== Prevent hyphenation locally ===
There are two ways to prevent a word from being hyphenated: the traditional {{tex|hbox}} and the more natural command {{cmd|nothyphenatedunhyphenated}}.
<texcode>
\hbox{myfragileword} % old-fashioned
\nothyphenatedunhyphenated{myfragileword} % MkIV, since 2013-04-21
</texcode>
