\mbox{oddword}
(Plain TeX users should use \
hbox
, and take care at the start
of paragraphs.) However, boxing the word is not really advisable
unless you are sure it only occurs once.
\hyphenation{oddword}
This hyphenation exception (with no break points) will be used in preference to what TeX’s hyphenation algorithm may come up with.
In a multilingual document, repeat the exception specification for each language the word may appear in. So:\usepackage[french,english]{babel} \selectlanguage{english} \hyphenation{oddword} \selectlanguage{french} \hyphenation{oddword}
(note that babel will select the default language for the
document — English, in this case — at \
begin{document}
.)
\
uchyph
is designed for suppressing such
behaviour:
\uchyph=0
will stop hyphenation of upper-case words. (Note that Plain TeX syntax is needed here: there’s no LaTeX alternative for setting this value.)
