<h1> Conjunction: Coordination</h1>
|
|
|
|
Coordination is defined for many different categories; here is
|
|
a sample. The rules apply to <b>lists</b> of two or more elements,
|
|
and define two general patterns:
|
|
- ordinary conjunction: X,...X and X
|
|
- distributed conjunction: both X,...,X and X
|
|
<p>
|
|
<p>
|
|
<tt>VP</tt> conjunctions are not covered here, because their applicability
|
|
depends on language. Some special cases are defined in
|
|
[``Extra`` ../abstract/Extra.gf].

ConjS : Conj -> [S] -> S ; -- "he walks and she runs"
|
|
ConjRS : Conj -> [RS] -> RS ; -- "who walks and whose mother runs"
|

ConjAP : Conj -> [AP] -> AP ; -- "cold and warm"

ConjNP : Conj -> [NP] -> NP ; -- "she or we"

<h2> Categories</h2>
|

These categories are only used in this module.

<h2> List constructors</h2>
|
|
The list constructors are derived from the list notation and therefore
|
|
not given explicitly. But here are their type signatures:
|
|
<pre>
|
|
-- BaseC : C -> C -> [C] ; -- for C = S, AP, NP, Adv
|
|
-- ConsC : C -> [C] -> [C] ;
|
|
}
