I am half native speaker..

Panjabi (or Punjabi) Language and its Scripts

 

Panjabi has two different scripts:

Gurmukhi – Primary writing Method in Eastern or Indian Panjabi (ਪੰਜਾਬੀ, ਗੁਰਮੁਖੀ)

Shahmukhi – Primary writing Method in Western or Pakistani Panjabi (شاہ مکھی)

based on Arabic script.

Panjabi is spoken only one way. Every Native Panjabi speaker in the world can

listen, understand and talk with each other, but when it is time to write in one

of above said scripts, then native speaker can only write or read it either 

Eastern/Indian or Western/Pakistani.

This way Panjabi is one of rare languages, which is written in such scripts that native

speaker can write or read in one script, but not other.

You can rarely find a person, who can read both script for Panjabi.

I am native Panjabi speaker, but able to write only in Gurmukhi script 

(that is Eastern/India Punjabi). I can’t even read Panjabi written 

Shahmukhi (Western/Pakistani) script at all.

So I am half native Panjabi.

You can rarely find a person, who can read both script for Panjabi.
