I don't know what that words means, and I'm in a public place so I don't think I'll look it up
I'll just type it out for you.
They're the 'dere' archetypes in anime and stuff. 'Dere' comes from 'deredere' which means 'lovey-dovey.'
You have:
Tsundere, tsun means hate, so it's the girls that pretend to hate the guy they like. Think Asuka in EVA, or Helga in Hey Arnold.
Yandere, Yan refers to insanity, literally "love you to death" Gasai Yuno from Mirai Nikki is the best example.
Kuudere, Kuu is 'cool' or 'coy,' Think CC from Code Geass, or Horo from Spice and Wolf. Usually mentally mature girl/woman.
Dandere, Dandere is the blank slate, rarely show emotion, and they display affection in very strange ways, think of Yuki from Haruhi, or Yin from Darker than Black.
Deredere, Lovey-dovey, usually a childhood friend, best example is Sumika from the Muv-Luv trilogy, or Uesugi Kenshin from the Rance games.
and Kanedere, Kane means money, so literally loves money, essentially a gold digger, think Nami from One Piece, or Fujiko from Lupin the 3rd.
There are surely a couple others, but those are the most commonly seen ones. You can apply this to just about EVERY girl (and some guys too, there are Tsunderes among men and stuff too) that appears in Japanese media, however some are hard to pin down, like Senjougahara from Bakemonogatari, they call her a "Tsundere" in a rather tongue in cheek kinda way, but she's more of a Kuudere if you really think about it, though, she also has Yandere qualities. If you can't pin them down to one archetype that means it's a well written character.
Who agrees on 4 FE characters?
Wolf and Lucas are NOT clones! They just have similar special moves compared to Fox and Ness, respectively! Their A attacks (save a few exceptions) are very much different.
4 is possible but not likely. Also if we get 4 is should be Marth, Ike, Chrom, Lyn
