<h1> Question: Questions and Interrogative Pronouns</h1>

<pre>
  abstract Question = Cat ** {
</pre>

A question can be formed from a clause ('yes-no question') or
with an interrogative.
<pre>
    fun
      QuestCl     : Cl -> QCl ;            -- does John walk
      QuestVP     : IP -> VP -> QCl ;      -- who walks
      QuestSlash  : IP -> ClSlash -> QCl ; -- whom does John love
      QuestIAdv   : IAdv -> Cl -> QCl ;    -- why does John walk
      QuestIComp  : IComp -> NP -> QCl ;   -- where is John
</pre>

Interrogative pronouns can be formed with interrogative
determiners, with or without a noun.
<pre>
      IdetCN    : IDet -> CN -> IP ;       -- which five songs
      IdetIP    : IDet       -> IP ;       -- which five
</pre>

They can be modified with adverbs.
<pre>
      AdvIP     : IP -> Adv -> IP ;        -- who in Paris
</pre>

Interrogative quantifiers have number forms and can take number modifiers.
<pre>
      IdetQuant : IQuant -> Num -> IDet ;  -- which (five)
</pre>

Interrogative adverbs can be formed prepositionally.
<pre>
      PrepIP    : Prep -> IP -> IAdv ;     -- with whom
</pre>

They can be modified with other adverbs.
<pre>
      AdvIAdv   : IAdv -> Adv -> IAdv ;    -- where in Paris
</pre>

Interrogative complements to copulas can be both adverbs and
pronouns.
<pre>
      CompIAdv  : IAdv -> IComp ;          -- where (is it)
      CompIP    : IP   -> IComp ;          -- who (is it)
</pre>

More <tt>IP</tt>, <tt>IDet</tt>, and <tt>IAdv</tt> are defined in <tt>Structural</tt>.
Wh questions with two or more question words require a new, special category.
<pre>
    cat 
      QVP ;          -- buy what where
    fun
      ComplSlashIP  : VPSlash -> IP -> QVP ;   -- buys what 
      AdvQVP        : VP  ->   IAdv -> QVP ;   -- lives where 
      AddAdvQVP     : QVP ->   IAdv -> QVP ;   -- buys what where 
  
      QuestQVP      : IP -> QVP -> QCl ;       -- who buys what where
  }
