He seems not to have grasped what i meant which greatly upsets me.

问题描述:

He seems not to have grasped what i meant which greatly upsets me.
meant是“意思,想法”吗可是“not to have grasp”不是已经表明了这个意思
还有先行词主语不是引导i表“他没有要抓我”那要meant不是多余了吗

他似乎没有抓住我的意思,(这件事)这使我大大不安.
what i meant 是宾语从句,which greatly upsets me.是非限性定语从句
upset 七上八下,颠三倒四.
