The mapping of space onto the domain of benefaction and some unpredicted trends in semantic change.

Morphemes that encode the semantic role of Beneficiary display complex patterns of polysemy. Such patterns have arisen through diachronic processes which are for the most part still unexplored. In the paper I discuss common assumptions about the directionality of semantic extension and about expected and unexpected polysemies. I show that, next to the often mentioned polysemy of Beneficiary, Recipient, Purpose and Direction, another frequent pattern includes Beneficiary, Purpose and Cause. Morphemes that exhibit such polysemy have original spatial meanings which include Location or Path, but not Direction. Notably, such original spatial meanings have been dropped in the course of semantic developments described in the paper. After discussing some well-attested diachronic developments, I show that, at least in the languages of Europe, markers of Beneficiary, Purpose, and Cause underwent an unpredicted semantic extension that led them to also indicate Direction. Such extension provides evidence for a rare development that has led a concrete spatial concept to be denoted by a morpheme that had an abstract meaning. [ABSTRACT FROM AUTHOR]
