<p>utrecht</p> <p><b>New page</b></p><div>'''Function composition''' is an algebraic notion which DiSciullo &amp;amp; Williams (1987) adopt from [[Categorial Grammar]] to account for an important difference between [[compounding]] and [[affixation]]. In compounding the non-head satisfies a [[theta-role]] of the [[head]]. The non-head of a complex word headed by an affix, however, does not satisfy a theta-role of the affix; rather the affix and the stem form a composed [[argument structure]]. In order to be able to relate the argument structure of an affixal head to its non-head, they propose that suffixes are [[functor]]s with respect to their [[complement]]s.<br /> <br /> === Example ===<br /> <br /> The English adjective ''complete'' has a Theme as its the external argument, and the nominal suffix -''ness'' the &quot;degree&quot; argument R, as in (i). Since -''ness'' is assumed to be a functor, function composition yields the composed argument structure in (ii):<br /> <br /> (i) complete -ness =&amp;gt; (ii) completeness<br /> (Th) (R) ((Th) R)<br /> functor<br /> <br /> === Link ===<br /> <br /> [http://www2.let.uu.nl/UiL-OTS/Lexicon/zoek.pl?lemma=Function+composition&amp;lemmacode=765 Utrecht Lexicon of Linguistics]<br /> <br /> === References ===<br /> <br /> * Di Sciullo, A.
