The names Dorothy and Theodore are both derived from the Greek words δῶρον, meaning “gift”, and θεός, meaning “god”. The only difference, etymologically, is that in Dorothy, the order is δῶρον + θεός, whereas in Theodore, it’s θεός + δῶρον.
Are there any other examples of pairs of personal names where the etymological constituents are reversed?
I looked up a few possibilities, including “Phillip and “Hippophile” (no one I can find with the latter as a personal name),
The closest I’ve gotten is “Roger” (“ruling spear”) and Gerald/Gerard (“spear ruler”). The “spear” part is cognate, but unfortunately the “rule/power” part seems to be from distinct words (“hrod” vs. “wald”). So close!
Slavic first names Miroslav and Slavomir (e.g. Russian: Мирослав, Славомир; Polish: Mirosław, Sławomir). The components mir and slava mean, respectively, “peace/world” and “glory”.
Here’s one pair that fits your criteria exactly: Bertram and Rambert
Bertram means “bright raven”, derived from the Germanicelementberaht “bright” combined with hramn “raven”.
Rambert: Derived from the Germanicelementshramn “raven” and beraht “bright”.
