I almost understand the Japanese system of suffixes, i.e., sensei, sempai, sama, san, chan, kun, etc. However, one instance seems to violate the normal pattern. I know some of you know the language, so maybe you can help me understand this question from season 1 of Card Captor Sakura: When addressing Sonomi Daidoji (Tomoyo's mother), Fujitaka Kinomoto (Sakura's dad) calls her "Sonomi-kun." I noticed this in the episode with the Flower Card, when Sonomi and Fujitaka meet at the school athletic festival.
I'm used to seeing -kun attached to younger male characters, i.e., Syaoran-kun, so what's up with this?
