Pronominal adverbs in German, which consist of da ‘there’, hier ‘here’, or wo ‘where’ as first element and a preposition as second element, like davor ‘before’, hierbei ‘hereby’, worin ‘wherein’, have often been explained by a movement of the first element out of the complement position of the preposition. This article points out some of the problems of movement analyses and presents an alternative account based on the diachronic development of pronominal adverbs. It is argued that the pattern after which pronominal adverbs are formed can be traced back to the univerbation of two adverbs with spatial meaning. This is accompanied by processes often associated with grammaticalization, such as semantic bleaching, phonological reduction, and a loss of separability in the standard variety. Some of the reduced forms are obligatory in phrasemes and particle verbs, thus constituting a split which can occur during grammaticalization. The reduction of the first element of pronominal adverbs and a doubling of the first element can be seen as part of a grammaticalization cycle.

德语中的代词副词，由da 'there'、hier 'here' 或wo 'where' 作为第一个元素和介词作为第二个元素组成，例如davor 'before'、hierbei 'hereby'、worin 'wherein'、have通常可以通过第一个元素移出介词的补语位置来解释。本文指出了运动分析的一些问题，并根据代词副词的历时发展提出了另一种解释。有人认为，代词副词的形成模式可以追溯到两个具有空间意义的副词的单动词。这伴随着通常与语法化相关的过程，例如语义漂白、语音还原以及标准变体中可分离性的丧失。一些简化形式在短语和助词动词中是强制性的，从而构成语法化过程中可能发生的分裂。代词副词第一个元素的减少和第一个元素的加倍可以被视为语法化循环的一部分。
