If you don't want to do it yourself, you'll need a script that does this for
you. This script will have to look up each word in the definition in the
database. You could do something like this:

$word = 'things';

// get definition from database
$result = mysql_query("SELECT definition FROM words WHERE word='$word'");
$definition = mysql_result($result, 0, 'definition');

// split definition in words
$words = explode(' ', $definition);

// look up each word
for ($i=0, $i<count($words); $i++) {
	$result = mysql_query("SELECT word FROM words WHERE word='".
	if (mysql_num_rows($result)==1) {
		// this word has a definition
		// make a link
		$words[$i] = '<a href="glossary.php?word='.$words[$i].'">'.

// join the words and tags
$linked_definition = join(' ',$words[$i]);

// display results
echo "Word: $word<br>\nDefinition:<br>\n$linked_definition";

This obviously isn't very efficient. For each pageview, the script has to
link the definition. You might want to run the script once, and then save
the linked definitions in the database. The glossary script then just has to
display the definition.
