Inflectional languages, and Romance languages in particular, display morphological variation in plural marking within the nominal domain. While standard varieties show plural inflection on all the constituents within the DP, other varieties show this plural marking only on some of its constituents. We investigate a set of puzzling data and propose that Number in Romance is not a head, but an adjunct, an optional and bi‐valent morphosyntactic feature. We single out the hypothesis that, within the nominal domain, the pluralizer is in unmarked cases adjoined to D (i.e., a categorized d root), and in marked cases it is adjoined to a noun or an adjective (i.e., a categorized n/a root). We also discuss that instantiations of plural marking within the nominal domain should be conceived as the output of morphophonological concord, a post‐syntactic operation that is sensitive to c‐command.

论罗曼史中数的句法

屈折语言，尤其是罗曼语语言，在名词域内显示复数标记的形态变化。虽然标准变体在 DP 中的所有成分上显示复数变化，但其他变体仅在其某些成分上显示这种复数标记。我们调查了一组令人费解的数据，并提出“浪漫中的数字”不是一个中心词，而是一个附属物，一个可选的二价形态句法特征。我们挑出一个假设，即在名词域内，复数词在未标记的情况下与 D 相邻（即分类的 d 根），在标记的情况下它与名词或形容词相邻（即，分类的 n/一个根）。我们还讨论了在名义域内复数标记的实例化应该被认为是形态语音协和的输出，
