According to research, there are more than 7,000 languages in the world, and their number is decreasing day by day. UNESCO designated February 21, 1999, as International Mother Language Day. This was done to help linguistic and cultural diversity and to honor the efforts of students at universities in Dhaka before the independence of Bangladesh to recognize Bengali as the second official language of India. Mother tongue plays an important role in literary creations in this language or other languages used by poets and writers. An example of this is Nizami Ganjai, whose mother tongue is Kurdish, and who is greatly influenced by Kurdish words, idioms, proverbs, and even tales in his poems.
