many和many a能作代词吗?

many,much,a little,a few这些词都是代词,可以作定语吗?他们也有形容词词性啊!作定语时是不是算形容 many 作代词主语谓语用单数还是复数. a many 和 many a 的用法? many things 是不定代词吗 many和various能连用吗? 关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致吗?比如：many peo many和a lot of一样吗 many 为不定代词属于零冠词范畴,为什么会有many a person 这种说法. many能修饰比较级吗 a great many和a great many of有区别吗? a great many of和a great many Many a 和a good many ,它们有什么区别
