<span id="g_t_0040abbr_007babbreviation_005b_002c-meaning_005d_007d"></span><h4 class="subsection">7.1.13 <code>@abbr</code>{<var>abbreviation</var>[, <var>meaning</var>]}</h4>
<span id="abbr"></span><span id="index-abbr"></span>
<span id="index-Abbreviations_002c-tagging"></span>
<p>You can use the <code>@abbr</code> command for general abbreviations. The
abbreviation is given as the single argument in braces, as in
‘<samp>@abbr{Comput.}</samp>’. As a matter of style, or for particular
abbreviations, you may prefer to omit periods, as in
‘<samp>@abbr{Mr} Stallman</samp>’.
</p>
<p><code>@abbr</code> accepts an optional second argument, intended to be used
for the meaning of the abbreviation.
</p>
<p>If the abbreviation ends with a lowercase letter and a period, and is
not at the end of a sentence, and has no second argument, remember to
use the <code>@.</code> command (see <a href="Ending-a-Sentence.html">Ending a Sentence</a>) to get the
correct spacing. However, you do not have to use <code>@.</code> within
the abbreviation itself; Texinfo automatically assumes periods within
the abbreviation do not end a sentence.
</p>
<span id="index-_003cabbr_003e-and-_003cabbrev_003e-tags"></span>
<p>In TeX and in the Info output, the first argument is printed as-is;
if the second argument is present, it is printed in parentheses after
the abbreviation. In HTML the <code><abbr></code> tag is used; in Docbook,
the <code><abbrev></code> tag is used. For instance:
</p>
<div class="example">
<pre class="example">@abbr{Comput. J., Computer Journal}
</pre></div>
<p>produces:
</p>
<div class="display">
<pre class="display"><abbr title="Computer Journal">Comput. J.</abbr> (Computer Journal)
</pre></div>
<p>For abbreviations consisting of all capital letters, you may prefer to
use the <code>@acronym</code> command instead. See the next section for
more on the usage of these two commands.
