<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>&#167;1. Traversing for primary verbs. </b>The story so far: the <a href="../supervisor-module/index.html" class="internal">supervisor</a> module has arranged for the source
text to be read in by <a href="../words-module/index.html" class="internal">words</a> and has made a rudimentary parse tree for
it using <a href="../syntax-module/index.html" class="internal">syntax</a>. Certain "structural" sentences, such as headings, have
been taken care of, and turned into nodes with types like <span class="extract"><span class="extract-syntax">HEADING_NT</span></span>.
</p>
<p class="commentary">But the assertions we want to read &mdash; such as "The Mona Lisa is in the Louvre",
or "The plural of major general is majors general" &mdash; are all simply
<span class="extract"><span class="extract-syntax">SENTENCE_NT</span></span> nodes with no children. The following traverse begins Inform's
compilation process in earnest: for each such <span class="extract"><span class="extract-syntax">SENTENCE_NT</span></span> node, it asks
the <a href="../linguistics-module/index.html" class="internal">linguistics</a> module to identify a primary verb, noun phrases and so
on, placing them in a subtree.
</p>
<p class="commentary firstcommentary"><a id="SP2" class="paragraph-anchor"></a><b>&#167;2. Textual sentences. </b>"Textual" sentences are not really sentences at all, and are just double-quoted
text used in isolation &mdash; Inform sometimes recognises these as being implicit
property values, as for the description of a room just created. These sentences
are necessarily exempt from having a primary verb.
