Final answer:
The Punjabi language was promoted in pre and post independence through educational institutions and social movements.
Step-by-step explanation:
In both pre and post independence, the Punjabi language was promoted through various means. One of the key ways in which Punjabi was promoted was through the establishment of educational institutions that focused on teaching the language. For example, in pre-independence India, the Singh Sabha Movement played a significant role in promoting Punjabi language and Sikh culture. Post-independence, the Punjabi Suba movement in the 1950s and 1960s led to the formation of the state of Punjab, which further supported the promotion and development of Punjabi language and culture.
