What does Madeline mean in Japanese?

Answer 1

It's not Japanese so nothing in particular. However, it may be used to refer to a type of small French cake (Madeleine) popular in parts of Asia, particularly Japan.

Answer 2

There is no direct translation for "Madeline" in Japanese since it is a name. Names are often written in katakana, a phonetic script used for foreign words and names, to represent the sounds of the original name. In this case, "Madeline" would be written as マドリン (Madorin) in Japanese katakana.
