Ways to determine whether a noun phrase is plural So in a recent answer someone told me:

预言 here most likely is not plural - hence the whole 的大


Which brings to mind a question about other ways of determining plurality. Certainly I've heard of using 們 as in 他們 and I know that 的 acts as a possessive and plurality is then based on the subject (n.)的... 

Are there other common plurality indicators?
I figured this deserved more than a comment.

Another big indicator of plurality would be 都 - 都 means: all - so obviously it can't be all of one. 

...孩子都... all the kids

...老虎都... all the tigers

...啤酒都... all the beers
