The structure of plural last names in Spanish and other languages

Spanish plural last name noun phrases appear with a determiner and singular or noun. Last names marked as are interpreted group, whereas ones collection of individuals (additive reading), although both behave like fully DPs. Based on comparison first names, I propose that involve null nominal ‘group’ head dominated by an associative realized the morpheme determiner. When is plural, it has additional NUM forces additive reading. The number patterns shown to be similar those N-N compounds, which they share other similarities. paper also surveys crosslinguistic pluralization patterns, proposing potential variation: presence/absence structural location head.
