The suffix -cağız comes to some nouns and gives the meaning of "feeling sorry, pity and compassion 

It is  formed of  suffixes  cak + az --> cağız 

Adam + cağız --> poor man 

* Note that this form should be used in a complete sentence.

* Note that this suffix can be used only with few nouns, not with all nouns. And it may NOT always sound good wıth person names. So it is better to  use the adjective "zavallı" with person names ;

Zavallı Ali --> Poor Ali
