<p>You can use the <code class="code">@abbr</code> command for general abbreviations. The
abbreviation is given as the single argument in braces, as in
&lsquo;<samp class="samp">@abbr{Comput.}</samp>&rsquo;. As a matter of style, or for particular
abbreviations, you may prefer to omit periods, as in
&lsquo;<samp class="samp">@abbr{Mr} Stallman</samp>&rsquo;.
</p>
<p><code class="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 class="code">@.</code> command (see <a class="pxref" href="Ending-a-Sentence.html">Ending a Sentence</a>) to get the
correct spacing. However, you do not have to use <code class="code">@.</code> within
the abbreviation itself; Texinfo automatically assumes periods within
the abbreviation do not end a sentence.
</p>
<a class="index-entry-id" id="index-_003cabbr_003e-and-_003cabbrev_003e-tags"></a>
<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 class="code">&lt;abbr&gt;</code> tag is used; in DocBook,
the <code class="code">&lt;abbrev&gt;</code> tag is used. For instance:
</p>
<div class="example">
<pre class="example-preformatted">@abbr{Comput. J., Computer Journal}
</pre></div>
<p>produces:
</p>
<div class="display">
<pre class="display-preformatted"><abbr class="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 class="code">@acronym</code> command instead. See the next section for
more on the usage of these two commands.
