I must quote what Dominus wrote some time ago on my talk page when I translate I use Province of Lower Silesia etc However here on Wikipedia I have to go with decisions made long ago The problem is that Wikipedia is increasingly used for reference by people who are not translators They should be aware that in real life the use of voivodeship results in confusion as foreigners usually have no idea what this word means Some Polish people may not care about it because Polish is a reader responsible language so Polish authors do not need to write understandably because readers are responsible for understanding By contrast English is a writer responsible language i e writers in English are responsible for making their texts understandable I wrote about the classification and some other problems related to translation in my article pages 101 104 Importantly this is reflected in the Wikipedia Manual of Style as one of the five general principles of Wikipedia is Clarity Writing should be clear and concise Plain English works best avoid jargon and vague or unnecessarily complex wording Voivodeship is jargon understandable nearly exclusively to Polish people I started a similar discussion in Wikipedia many years ago but I was quickly defeated by people saying that a consensus has been reached and now it s too late I wish I was more experienced then and knew that voivodeship is against the principles of Wikipedia
