Titles and Honorifics:
- -dono: That honorific that particularly humble or traditional characters use. If you watch anime that are set in the Meiji era (or older) you may be familiar with this. Souma uses this as he's the traditional type.
- Buchou: Club Leader. Considering that I've already used "Buchou" a few times, it would be weird for me to start translating it now, so I'm still keeping it as Buchou.
Character Speech Patterns:
- Souma speaks very humbly and traditionally, and goes as far as to speaking words in Katakana in Hiragana instead (which I've interpreted as him having a thick accent that has difficulty with "borrowed words" though your mileage may vary). He uses uncommon words and phrases and even uses some old forms such as using -nu instead of -nai for negatives, and saying "de aru" instead of "desu"
- Kanata... speaks entirely in Hiragana, without using kanji at all and turning Katakana into Hiragana as well. I've learned that this seems to be showing how he speaks very slowly/whimsically (if you've listened to the drama on the Ryuseitai single, you'll understand what I mean).
