Etymology
Misinterpretation of. When the old ablative cases of, eōd, eād, became eō, eā, the true forms eōd-em, eād-em were interpreted as eō-dem, eā-dem. The neuter nominative singular id-em is natural and gives earlier emem (= later eundem). The new marker -dem then served to create, , , etc. Compare with its later doublet:  (← *tam-dem).
