Metaphor forces argument overtness

This paper uncovers how metaphor forces argument overtness - across languages and parts of speech. It addresses the relationship between semantically unsaturated terms, functors, and the argument terms that complete them. When the component terms' default senses clash semantically, a metaphor arises. In such cases, the argument must be overt, in contrast to literal uses. It is possible to say Everyone was waiting at the hotel. Finally, Kim arrived. By contrast, people do not use arrived metaphorically without a goal argument: Everything had been pointing to that conclusion all along. *Finally, Kim arrived. What they say is Finally, Kim arrived at it. We illustrate the phenomenon with powerful and diverse evidence: three corpus studies (Indo-Aryan languages, British English, Vera'a) and a sentence-completion experiment with around 250 native speakers of English. Both the corpus studies and the experiment show no or almost no exceptions to metaphor-driven argument overtness. The strength of the effect contrasts with a complete lack of speaker awareness. We propose that metaphor-driven argument overtness - as well as the lack of speaker consciousness - is a universal phenomenon that can be accounted for in terms of human language processing.
