有连字符的组合词(如two-year-old)是什么词性

my son's two-year-old 和 my son's two year old 有什么区别？

老师，请问有连字符的组合词（连字符这个杆是不能省略吗）的词组（或短语）一般作什么成分，是不是所有有杆组合的词组（或短语都是有名词或形容词性词特性？

除形容词外，还有哪些词性词组有杆词语的组合吗？

有些连字符的词组（或短语）这杆能省略不？

two-year-old是作前置定语的形容词形式，也可以是名词。不能作表语。因此你的第一个句子用其做表语是错的。第二个句子表语应为two years old.

two-year-old作名词时，复数形式为two-year-olds。

My two-year-old son is very clever.

There are several two-year-olds in the daycare centre.

复合名词带连字符、不带连字符还是直接拼写在一起主要由习惯决定。最好的办法还是查词典。如basketball, papar tiger, pencil-box

复合形容词由连字符连接最常见于作者自己临时杜撰的形容词. 如 He wrote to his friend in good-good-study English.
