The paper makes the following novel claims: (1) the semantics of noun-noun compounds which is activated by metaphor and/or metonymy (often termed as "exocentric" compounds in linguistics and generally regarded as semantically opaque) can be accounted for with the help of conceptual metaphor and metonymy theory; (2) there are regular patterns of metaphor-and metonymy-based compounds, depending on which constituent is affected by conceptual metaphor and/or metonymy. In the second part of the paper I look at a subtype of metaphor-and metonymy-based noun-noun compounds, where the simultaneous activation of both metaphor and metonymy affects the meaning, and give an account of the productive patterns that underlie this type.
Introduction: the problematic nature of exocentric compoundsNoun-noun compounds are a highly intriguing set of linguistic phenomena. Not only do they form the largest group of compounds in English (Algeo 1991), 1 but children learn to produce this type of compound the earliest, from around the age of two (Clark 1981). However, what is most remarkable about these compounds is the diversity of semantic relationships that can exist between the two components on the one hand, and between the individual elements and the compound as a whole on the other. Nevertheless, however diverse the semantics of noun-noun * I wish to thank my reviewers for the excellent remarks and observations. I am also grateful to Zoltán Kövecses, who has meticulously read through several earlier versions of this paper. Needless to say, all remaining errors are mine. The publication of the paper was supported by the Research Group for Theoretical Linguistics of the Hungarian Academy of Sciences at the University of Debrecen.1 A fifty-year-long research into the emergence of new words in the United States (Algeo, op.cit.) has managed to shed some light on contemporary word formation patterns. According to the data, compounding is the most productive word formation process: 68% of the new expressions were grouped into that category. More interestingly, 90% of the compounds were nouns. combinations may be, many linguists have attempted to systematise the constraints that apply in their creation and interpretation (see for example Adams 1973;Downing 1977;Jespersen 1954;Levi 1978;Marchand 1960;Ryder 1994;Warren 1978).The most traditional and pervasive semantic classification of compounds used in linguistics is based upon the work of Bloomfield (1933), who suggested that compounds fall into two main groups. In endocentric constructions, the compound is the hyponym of the head element: apple tree is a kind of tree. In the case of exocentric or "headless" constructions, however, the compound is not a hyponym of the head element, and in the majority of cases there is some sort of metaphor or metonymy at work in the meaning of the compound. For example, blue-stocking does not denote a kind of stocking but refers to a well-educated woman. While the terms endocentric and exocentric are often used in linguistics even today (see for ...
