#structural spelling

• Alvez — An orthographic variant or rare form for the Hispanic surname 'Alves' or 'Alvarez'; an anthroponymic proper name used within Ibero-American communities. Although the spelling with a final 'z' is less frequent than the standard Portuguese variant with 's', it appears officially fixed in international civil registries.
• Arianizm — An old, archaic spelling variant or one influenced by Polish or Cyrillic transliteration of the word 'arianism'; it denotes the same heretical doctrine in early Christian history initiated by Arius. In historical texts or manuscripts from the 18th and 19th centuries, the term appears written with a 'z', reflecting the structural phonetic norms of that era prior to modern academic spelling stabilization.
