(By Michael Daniel): "Somewhat paradoxically, the plural of personal pronouns has been considered both as a core phenomenon of nominal number and as something that has nothing to do with it. On the one hand, several scholars have suggested that if a language has a number distinction anywhere, then it has it at least in pronouns, or, speaking in diachronic terms, that plurality has spread from plural personal pronouns to other nominals (cf. Forchheimer 1953). On the other hand, linguists have repeatedly argued that pronominal plurals are different from nominal plurals in that the two have a different reference structure. Thus, it is observed that ‘we’ is not the same as ‘I + I + … I’ (e.g. Benveniste 1966a, Barulin 1980; cf. also Corbett 2000: 83-84). This chapter provides an account of what types of formal correlations between plurals and singulars are actually observed in personal pronouns, and how the devices for expressing pronominal plurality relate to the devices for expressing nominal plurality. It is based on 260 languages, including the 200 languages of the WALS sample, and will thus contribute further empirical data to the discussion."
