First notebook entry: Introducing myself

mai punjabi sikhna chaundi hu haan kyoki mainnu ae language zabaan (Pak), bhasha (Ind), boli (both) bahut vadhiya lagdi e si......

"hun" is Hindi-Urdu; in Punjabi it's either "haan" (nasal ã) or "va"

"lagdi si" is the imperfecte past ("I was liking it"), I don't think it makes much sense in this context.

 
Try writting in Gurmukhi or Shahmukhi script next time:
 

ਮੈਂ ਪੰਜਾਬੀ ਸਿਖਨਾ ਚਾਹੁੰਦੀ ਹਾਂ ਕਿਊਂਕਿ ਮੈਨੂਂ ਇਹ ਭਾਸ਼ਾ ਬਹੁਤ ਵਧੀਆ ਲਗਦੀ ਏ.
