The <CODE>NP VP</CODE> predication rule form a clause whose linearization
|

gives a table of all tense variants, positive and negative.

Clauses are converted to <CODE>S</CODE> (with fixed tense) in <A HREF="Tensed.html">Tensed</A>.

Using an embedded sentence as a subject is treated separately.
|
|
This can be overgenerating. E.g. <I>whether you go</I> as subject
|
|
is only meaningful for some verb phrases.

This category is a variant of the 'slash category' <CODE>S/NP</CODE> of
|
|
GPSG and categorial grammars, which in turn replaces
|
|
movement transformations in the formation of questions
|
|
and relative clauses. Except <CODE>SlashV2</CODE>, the construction
|
|
rules can be seen as special cases of function composition, in
|
|
the style of CCG.
|
|
<B>Note</B> the set is not complete and lacks e.g. verbs with more than 2 places.

<H2>Imperatives</H2>
|

<P>
|
|
An imperative is straightforwardly formed from a verb phrase.
|
|
It has variation over positive and negative, singular and plural.
|
|
To fix these parameters, see <A HREF="Phrase.html">Phrase</A>.

Sentences, questions, and infinitival phrases can be used as

subjects and (adverbial) complements.
