A compositional account of the semantics of German prefix verbs in HPSG is out- lined. We consider only those verbs that are formed by productive synchronic rules. Rules are fully productive if they apply to all base verbs which satisfy a common de- scription. Prefixes can be polysemous and have separate, highly underspecified lexical entries. Adequate bases are determined via selection restrictions. 1 The Problem Determining the semantics of unknown words which can be derived from lexicon entries is highly de- sirable for natural language understanding (Light, 1996). In this paper, I sketch a compositional ac- count of the semantics of German prefix verbs de- rived from a verbal base, concentrating on those verbs that can be generated by a productive word formation rule. Like (Witte, 1997...
