The work consists of two parts. The first part deals with the phonemic analysis of Hindi and Punjabi followed by a comparison of the phonemic systems of the two.
A plan Like this would naturally involve some sort of repetition, but it was essential to state the phonemics of Hindi and Punjabi separately, this being the first attempt in this direction, before a phonemic comparison could be made.
The second part is comparative study of the evolution of Hindi and Punjabi phonology.
The main attempt is to show the mutual agreements and disagreements between the two languages in their treatment of different old Indo-Aryan and Middle Indo Aryan sounds.
This study reveals the relationship between these languages in the past, their influence on each other and mutual present here whether in the MIA or NIA stage.
