Partial or complete lack of plural agreement

Many Romance languages and varieties show different patterns of partial or complete lack of plural agreement within the determiner phrase (DP). This phenomenon has scarcely been addressed in the literature and poses problems for any kind of analysis proposed so far, regardless of the theoretical background. This paper presents and classifies several cases of lack of plural agreement or plural marking within the Romance DP and critically discusses several proposed analyses in research literature and their applicability to these Romance varieties. The main focus of the discussion is placed on the role which morphology is assumed to play. It is argued that lack of plural agreement can be explained neither in pure syntactic terms nor in pure morphological terms.
