多相(polymorphism)や単相(monomorphism)の morph の説明で様相という言葉を使っていますが、型まわりで様相という語をつかうと、様相型システム(modal type system)等の様相(modality)とまぎらわしいので、単に「相」とした方がよいと思います(「相」といっただけで意味が通じるか不安だったので括弧書きで説明をつけていますが、なくてもよいかもしれません)。
参考までに『型システム入門』では「poly = many = 多、morph = form = 相」(p.267, 23.2 さまざまな多相性)のような説明をしています。
強いて二字の語を選ぶなら「形相(けいそう)」などがあたるのではないかと思います。
