How best to write about love and other things. Nabeela Ahmed talks about writing in a second language and how her early life in Kashmir shaped the language she uses to express different aspects of her life. She is also a champion for the Pahari language in her home city of Bradford. Pahari is a language spoken by people in Northern areas of India, Kashmir and Pakistant. It fell out of favour as an official language of the courts but is still widely spoken in many British Asian homes today. Nabeela works with groups of budding poets and writers to help them express themselves in whichever language they feel comfortable with alongside English.
