That’s “J” that is pronounced as a “Y” in English, not “L” which is pronounced as “Y”.
The Hungarian alphabet has 43 letters instead of 26 like in English.
“O” and “U” have 4 each (eg, O, O with a slash over it, O with two slashes over it, O with two dots over it, etc)
Hungarian also has letter combinations where two letters in English make one in Hungarian. For example
cs = ch sound in English, sz = s sound in English, etc
I always thought it was pronounced gouyash with a long a but I’m only half Hungarian and while I can speak the language I haven’t had much practice lately.
