 One student, Wanamisi Juma Karisa, stands out with a song about the beauty of the Swahili language. I sang today because I love Swahili, she tells me. More people should learn it. Swahili is one of more than 60 languages spoken in Kenya. It is the only official language other than English. In Kenya, it's a required second language. But Kenyan attitudes towards Swahili haven't always been positive.
