stressed 通常講述緊張的狀況, 雖然都是"adj", 但並不常用在名詞前面, 而 stressful就可用在名詞前面去形容這名詞, e.g. a stressful job。

這資料是在字典內找的 :
stressed 若用在 noun 前面只可以 "that has had a lot of physical pressure put on it e.g. stressed metal

它們都是形容詞, 在我來看差別是細微的, 亦有好多人並不太仔細, 兩者或三者都無分別的照用, 要看你是是否執著, 或有什麼特定用途 :
stressed : too anxious and tired to be able to relax
stressful : causing a lot of anxiety and worry

satisfying : giving pleasure because it provides something you need or want; e.g. a satisfying meal / experience
satisfactory : good enough for a particular purpose; e.g. a satisfactory explanation
satisfied : pleased because you have achieved something or because something that you wanted to happen has happened; e.g. a satisfied smile

beautiful 和 beauteous 的解釋是一樣, "beauteous" 是文言的用法, 就等於中文的白話和文言文一樣, 比較文化味的用 "beauteous"。
