<span id="tie"></span><span id="index-tie-_0028unbreakable-interword-space_0029"></span>

<span id="index-Non_002dbreakable-space_002c-variable"></span>
<span id="index-Unbreakable-space_002c-variable"></span>
<p>The <code>@tie{}</code> command produces a normal interword space at which
a line break may not occur. Always write it with following (empty)
braces, as usual for commands used within a paragraph. Here’s an
example:
</p>
<div class="example">
<pre class="example">@TeX{} was written by Donald E.@tie{}Knuth.
</pre></div>
<p>produces:
</p>
<div class="display">
<pre class="display">TeX was written by Donald E. Knuth.
</pre></div>
<p>There are two important differences between <code>@tie{}</code> and
<code>@w{ <!-- /@w -->}</code>:
</p>
<ul>
<li> The space produced by <code>@tie{}</code> will stretch and shrink slightly
along with the normal interword spaces in the paragraph; the space
produced by <code>@w{ <!-- /@w -->}</code> will not vary.
</li><li> <code>@tie{}</code> allows hyphenation of the surrounding words, while
<code>@w{ <!-- /@w -->}</code> inhibits hyphenation of those words (for TeXnical
reasons, namely that it produces an ‘<samp>\hbox</samp>’).
</li></ul>
