My definitions produce a slightly different result. I assume that "sentence" is the string and "last word" is the last string of 'word' characters. The "rest" is all the characters before the "last word". Note that the space before "last word" is included in 'rest'. Possible non-word characters after "Last word" are discarded.
#!/usr/bin/perl
use strict;
use warnings;
my $list = "This is my list";
$list =~ /
^(.+) # The 'rest' (Everything before last word)
\b # UPDATE (ref [eyespoplikeamosquito] below)
(\w+) # Last 'word' (string of contiguous word characters)
\W*$ # Possible non-word characters at end of string
/x;
my $last = $2;
my $the_rest = $1;
print $the_rest; # "This is my"
print $last; # "list";
<\c>
<p>RESULT:</p>
<c>
This is my list
UPDATE: Added explicit definition of 'sentence'.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
