Sorta... There are several common words (Like I, thank you, and possessive words) which have both a masculine and feminine version, even though they mean the same thing. This structure also extends to hierarchy like family and corporate ladder as well. That's why its easy to even say something like "You're Welcome" and either get weird looks cause you're using a feminine version when you're a guy, or you're and adult and use a young child's version). FF uses this alot, Sephiroth uses a very polite form of speech before the Nibelhiem incident but then switches to a very cocky and arrogant speech pattern. Kefka switches between a child's speech and an adults at random intervals. Both are used to signify to the reader that something has happened to their mental states.
