What's the difference between "voivodship" and "voivodeship" (noun)?

Solution 1:

While I agree this question is not in common usage in English I am not 100% sure voivodship exist or existed in other countries and then how do we write in English in historical books or write about nowadays Poland?

Voivodship refers also to Polish-Lithuanian Commonwealth (historical context) and might (this is my suspection) to other slavic countries in the past.

Quoting wikipedia: "Words for "voivodeship" in various languages include the Polish: województwo; the Romanian: voievodat; the Bulgarian: voivoda (войвода); the Serbian: vojvodina (војводина), vojvodstvo (војводство) or vojvodovina (војводовина); the Hungarian: vajdaság; the Belarusian: ваяводства (vajаvodstva); the Lithuanian: vaivadija. Some of these words, or variants of them, may also be used in English." https://en.wikipedia.org/wiki/Voivodeship

Let's finish discussion agreeing that there are multiple spellings in english for the same word
