Why bother to use the “correct” tengwar (since hardly anyone can tell the difference/since there are so many different interpretations)?
I’m about to get a bit preachy. You have been warned. Imagine a native French-speaker who doesn’t understand a word of English. (Note that most French-speakers know more than enough English to not do what I’m about to describe.) She happens to be a big fan of Tolkien, so she makes a Tolkien board. In order to honor the language in which Tolkien wrote, she decides to make her welcome banner in English, but she doesn’t know any English, so she randomly picks out words from her one book in English (which happens to be Tolkien’s The Two Towers).
