The DP-Domain in Germanic

The domain of the so-called Determiner Phrase (DP) includes the lexical noun as well as its associated determiners (articles, pronouns), numerals, quantifiers, and modifiers (adjectives, possessors, relative clauses, attributive PPs). The reason why nominals are referred to as DPs is the assumption that they are structurally headed by the determiner, or more precisely by the article, rather than by the noun itself. The lexical NP thus has an extended functional DP-layer. The specifier of D can be occupied by certain pronouns such as demonstratives, which are considered phrasal. In addition to the DP-layer, numerals, quantifiers, adjectives, and possessives constitute a series of further functional layers between D and N. Common features of the Germanic DP-domain are, to name but a few, an absent indefinite plural article, prenominal adjectives and possessive constructions like s-genitives, and possessor doubling. However, North and West Germanic differ considerably with respect to, for instance, definiteness marking, the placement of demonstrative reinforcers, and the unmarked position of possessive pronouns and possessor-DPs. It is these differences that pose a challenge to researchers who aim to find a unified structural analysis for the DP in Germanic. A common strategy to account for different word-order preferences are low base positions and movement: The unmarked position of possessive determiners is postnominal in North Germanic (huset hans ‘house.def his’, Norwegian) and prenominal in West Germanic (sein Haus ‘his house’, German). Therefore, the possessive pronoun is often assumed to be base-generated in a structurally low position. West Germanic possessives then precede the head noun by obligatorily rising to the DP-layer, while in North Germanic they (preferably) stay in situ. In the last 20 years, generative research on the syntax of less prominent as well as nonstandard Germanic varieties has gained momentum. Studies of this kind enable an additional perspective on phenomena that would be difficult to analyze if only the standard varieties were considered. For instance, the exact grammaticalization path of the reinforcement of the Proto-Germanic demonstrative *þo- by the interjection *sai must remain speculative due to the lack of Proto-Germanic data. A look at contemporary data can help: Some modern Germanic varieties show a similar reinforcement of demonstratives by locative adverbs (die do birdies ‘those there birds’, Pennsylvania German), which can serve as a blueprint for reconstructing the grammaticalization path of the Proto-Germanic reinforced demonstrative.
