LatinSuper, HittiteŠer, and the Indo-European Numeral ‘7’In this brief paper, it is argued that the initial*s- found in the Latin and perhaps Greek reflexes of the Indo-European adprep*uper(i)‘over, above’ derives from blending with another adprep of the same meaning,*ser(i). Evidence is also presented for the creation of another blend involving these two forms,*sep-, which may underlie the Indo-European root for ‘7’. This latter assertion is strengthened by typological precedent.
