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

• Zwinglïad (“a Zwinglian”, noun)
• Zwinglïaeth (“Zwinglianism”)
