Teacher: Now, understand the problem? Solve this instance: The Sahel (/ səˈhɛl /) is the ecoclimatic and biogeographic zone of transition in Africa between the Sahara to the north and the Sudanian Savanna to the south. Having a semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea. The name is derived from the Arabic word sāḥil (ساحل, Arabic pronunciation: (ˈsaːħil)) meaning 'coast' or 'shore' in a figurative sense (in reference to the southern edge of the vast Sahara), while the name Swahili means 'coastal (dweller)' in a literal sense.
