I found this word left which that mean stay or leave is very interesting 这句话的错误在哪？ 如何改

I found this word "left" which means stay or leave is very interesting .才对追问which 后面不是还要有个主词吗？ S+V追答不用
这是定语从句
先行词是"left"
which就代替了这个 "left"，在从句里面做主语追问你认为这个which 是主格？追答在定语从句中起到主语的作用追问上在这段话 好像有三个动词？ 但只有两个主语？found+means+is I+which?追答是的，很正常的found是主句动词，is是宾语从句的动词，means是定语从句的动词追问我觉得应该是这样的！
I found S+V
which+means S+V
word "left"is very interesting 前面的先行词 接 S+be.V

这才说的通！追答stay or leave这里做名词用，是用来解释left的意思追问left 后面的which means stay or leave 这一段是形容词子句 由which 所引导具有主词的属性，但同时which就代表了left对吧！ 前面还有个主词对is very interesting 也是一句话追答你对定语从句的理解完全是混乱的
which means stay or leave中的which代替了left

相当于left means stay or leave
