It seems very plausible. Having spent a great many years studying Spanish, I can say with some authority that the romance languages, French, Italian, Spanish, etcetera are largely descended from Latin, so there should be great similarities between them. Additionally, there was a conqueror named William of Normandy who took over large parts of England and likely spoke some sort of Romance/Latin/French thing from Normandy. Of course, he put his friends and comrades in charge of England with the result that their language became the language of the ruling class so people of the British Isles who were educated, were educated in that language. Thus, many words, especially the larger "educated" words, are similar all across Europe.
Well, I found a word. I won't give it all out so others can enjoy their own research, but it starts with a "gn" does that mean it is eclipsed? Is it a crude word? The country boy in me wonders if there are there different words for animal husbandry? Would they use the same word for sex in the phrase, "I breed holsteins with herefords," for example? It seems cow, bull, and steer all have different names, heifer on the other hand is different. Any Irish ranchers want to weigh in here?
