• Being derived from a proper name, Kantaidd does not have its spelling adapted to typical Welsh orthographic conventions, which do not use the letter k. See also Zwinglïaidd (“Zwinglian”).
• Like many other unnaturalised words recently derived from other languages, Kantaidd does not undergo initial mutation.
