- Country Name in Latin: Nederlandia or Batavia
- Name of inhabitants: Batavi or Nederlandenses
The Dutch may well want to avoid Batavia these days, but Batavophile is less of a mouthful than Nederlandophile. Marginally more hits on Google too (438 vs 299).
Hollandophile has 711 hits, which just shows how insensitive the world is to the concerns of the Eastern Netherlands.
Norway is Norvegia in Latin; although the entry has not been filled in on Latin Wikipedia, a Norwegian is Norvegus. So Norvegophile.
6 hits on Google. Though 154 for Norwegophile.
I leave any inferences to the reader…
