-Initial letters are typically a single letter, which can be selected by the <code>::first-letter</code> pseudo-element, as defined in [[SELECT]].
+Initial letters are typically a single letter, although
+they may include punctuation or a sequence of characters which 
+are perceived by the user to be a single typographic unit.
+The <code>::first-letter</code> pseudo-element, as defined in [[SELECT]], can be used to select an <a>initial letter</a>.
 
 <p>Authors who need more control over which characters are included in an initial letter, or who want to apply initial-letter formatting to replaced elements or multiple words can also apply the 'initial-letter' property to the first inline-level child of a block container.
