3 questions on 双つ and 悠旧
- Does 双つ = 二つ, just written with a character for twins in mind? Or does it mean something slightly different from the different character (in denotation only; I don't care about connotation)?
- Is 双つ read ふたつ or そうつ? My keyboard accepts そうつ, but Google and the Internet tells me it is ふたつ (http://www.kanjipedia.jp/kotoba/0004197700).
- Does 悠旧 = 悠久? If not, what does it mean (reading, definition)?
