α. Πέμπε, Æolic Greek.
β. Pump, Welsh. These account for the change from the n + t in πέντε to m + p.
γ. Fimf, Mœso-Gothic; fünf, Modern High German.
δ. Fem, Norse.
The change from the π- of πέντε to the qu- of quinque is the change so often quoted by Latin and Celtic scholars between p and k: ἵππος, ἵκκος, equus.
6. Six=ἓξ, sex.
7. Seven=ἑπτὰ, septem.
This form is difficult. The Mœso-Gothic form is sibun, without a -t-; the Norse, syv, without either -t- or -n (=-m). A doubtful explanation of the form seven, &c., will be found in the following chapter.
8. Eight=ὀκτὼ, octo.
