Explanation:

.The word Punjab is a compound of two words-Panj (Five) and aab (Water), thus signifying the land of five watrers or rivers. This origin can perhaps be traced to panch nada, Sanskrit for 'Five rivers' the word used before the advent of Muslims with a knowledge of Persian to describe the meeting point of the Jhelum, Chenab, Ravi, Beas, and Sutlej rivers, before they joined the Indus”.
