(Or, far more rarely, insert an incorrect hyphenation.) So, for documents with an unusual vocabulary or when fine-tuning for a printed edition, you may wish to help TeX out. Texinfo supports two commands for this: </p> <dl compact="compact"> <dt><span><code>@-</code></span></dt> <dd><p>Insert a discretionary hyphen, i.e., a place where TeX can (but does not have to) hyphenate. This is especially useful when you notice an overfull hbox is due to TeX missing a hyphenation (see <a href="Overfull-hboxes.html">Overfull “hboxes”</a>). TeX will not insert any hyphenation points itself into a word containing <code>@-</code>. </p> </dd> <dt><span><code>@hyphenation{<var>hy-phen-a-ted words</var>}</code></span></dt> <dd><p>Tell TeX how to hyphenate <var>hy-phen-a-ted words</var>. As shown, you put a ‘<samp>-</samp>’ at each hyphenation point. For example: </p><div class="example"> <pre class="example">@hyphenation{man-u-script man-u-scripts} </pre></div> <p>TeX only uses the specified hyphenation points when the words match exactly, so give all necessary variants, such as plurals. </p></dd> </dl> <p>Info, HTML, and other non-TeX output is not hyphenated, so none of these commands have any effect there. </p> </div> </body> </html>
