Traditionally derived from Proto-Indo-European * sámh₂-dʰ- (compare Ancient Greek ἄμαθος ( ámathos ) , ψάμμος ( psámmos ) , English sand , and possibly Old Armenian աւազ ( awaz ) ) with a diminutive suffix -ulum . However, according to the EIEC, such a reconstruction is phonotactically impossible. More recent scholarship considers the Latin to be from a European substrate , with the original form * (p)sam- or * sab⁽ʰ⁾- . Under this view, the terms listed with * sámh₂-dʰ- are cognate and derived from the same substrate continuum, but not the ones listed with * sem(h₂)- .
