[HPSG-L] Asking for help

[frank]

Hello, everybody. I need your help.


       I am researching a so-called marked language phenomenon "Light Verb Constructions"  like "take a walk, give a groan, make an inspection, give  a demonstration", etc. Based on Langacker's Foundations of CG(1991), eventive objects (Quirk's treminology ) can be called some 'nominalization' ---a second type designating a single episode of the process profiled by a perfective verb.
     Langacker also claimed in his  "Metonymy in Grammar" ( Foreign Languages, 2004, a journal published by Shanghai International Studies University) that  grammar is basically metonymic in nature.
      Nowadays I have found that some scholars   claim metonymy is absolutely the cognitive mechanism in the formation of nominalization.
    But certain scholar holds that regarding typical eventive nouns like "act, move, jump, kick", the counterpart of which are not eventive nouns in Chinese, but encoded as a verbal phrase. These eventive nouns denote simple acts. Wierzbicker (1982)  even called them "verbs" in constructions like "have a drink". So it seems hard to draw a clear boundary between process and result concerning the eventive nouns above.
  So  questions occur in my mind.
  In the formation of Light Verb Constructions, does metonymy still plays an important role? To what extent?
   No doubt, conceptual metaphor does work as they are coded.
 I will quite appreciate it if anyone could expalin it to me at your earliest convenience.
With best regards
                            Sincerely yours
                              Aipu
