There are as many ways to say my name as there are languages with a concept of the number 4, or 44 if you’d prefer. You can use any of these you feel comfortable with- some of 'em are really fun to say.
Japanese: I-shi-shi or I-shi-ju-shi
German: E-vier-vier or E-vier-und-vier-zig
Swahili: E-nne-nne or E-a-ro-bai-na-nne
And a personal favorite:
Maori: E-e-whā-e-whā, or E-whā-teh-kau-mah-whā
You could get even more crafty with it and try translating “double four” too, but I think I’ve already given a fair enough place to start.
Uh… No. Good guess though! If you have Return of the King (the Lord of the Rings, Vol. III) you should turn to the appendices and find the pronunciation guide.
