易错句子The proprietary of this land is still in dispute.
正确表达The ownership of this land is still in dispute.
proprietary 是形容词，意思是“与所有权有关的、专有的”，不能当名词单独使用。这里主语位置需要一个表示“所有权”的名词，应用 ownership（或 property）。中文里“专有”可作名词性成分，容易把 proprietary 直接当名词用。

正确表达She is very proprietary about her designs.
proprietary 表示“占有欲强的、不愿与人分享的”时，后面固定接介词 about，不接 to；用 to 会让人误解为“属于”的关系。表示对某物的独占态度要用 be proprietary about sth。
