I asked the follow-up question "but how did English settlers come to adopt the Dutch pronunciation?" This is what "he" said (by the way, "he" is an AI program):
During the colonial period, there was significant interaction between English settlers and speakers of other languages, including Dutch. Dutch settlers established colonies in what is now New York, New Jersey, and Delaware, among other areas. As a result, there was linguistic contact between English and Dutch speakers, leading to the exchange of words, phrases, and even pronunciation features.
It's important to note that language is not static and is constantly evolving, influenced by contact with other languages and cultures. In areas where there was significant interaction between English and Dutch speakers, it's likely that some linguistic features from Dutch, including the pronunciation of certain letters like "Z," were adopted by English speakers over time.
Additionally, English settlers in North America were part of a diverse population that included speakers of various languages and dialects. This linguistic diversity contributed to the development of American English as a distinct variety with its own unique features, including some influenced by Dutch pronunciation.
"He" also tells me that there wasn't a significant Dutch population in the UK during the colonial period.
Anyway, you get the general drift - apparently strange pronunciation is often due to borrowings from other languages, and isn't always a planned thing.
Fun fact: In Leicester, Belvoir Street is pronounced "Beaver Street." Nobody knows exactly why, but it's thought that people with the local dialect may have found it easier to say it that way.
Back on topic (kind of), one problem of "Zee" is the confusion it caused me when I heard the song "Oh, Lonesome Me" with the lyrics "I've thought of everything from A to Z" - as it was an American song, it was pronounced "ay to zee," and not knowing that Americans did the zee thing, I naturally thought he was singing "I've thought of everything from A to C." So I concluded that he needed to think a bit further than the first 3 letters of the alphabet, and that he hadn't tried hard enough and deserved to be lonesome. I can see why they've never rewritten the words for an English audience. Fixing the one problem creates several new problems.
