writer/artist of manga
Mangaka means "author of mangas" in Japanese. Ka is a suffix which means "artist" and its original meaning is "house" or "family" because in the old days, the activity of artists has perpetuated itself from generation to generation. You can also say "gaka" for "painter" and "ongakuka" for "musician".
Manga-ka (æ¼«ç”»å®¶) is the Japanese word for a comic artist. Outside of Japan, manga usually refers to a Japanese comic book and manga-ka refers to the author of the manga, who is usually Japanese. The -ka (å®¶) suffix implies some degree of expertise and a traditional kind of authorship.
