11) Ganaanci -
Spoken by native & non native hausa speakers in Ghana, Togo, Mali e.t.c
It must be noted that Hausa language has over the centuries become a widely used trade language in northern Nigeria and parts of the Middlebelt region of Nigeria, Niger republic, northern Ghana e.t.c and by so have developed many 2nd language speakers.
In Nigeria, hausa 2nd language/non-native/trade language speakers are found in Borno, Yobe, Adamawa, Plateau, Niger, Nasarawa, Taraba, Gombe, FCT, Southern half of Kaduna state, Southern 2/3 of Bauchi state and Southern 1/3 of Kebbi state.
The people of these places are not native hausa speakers and may be sometimes confused for native hausas by Southern Nigerians. However some of these northern minority groups are fastly loosing their own individual languages to hausas and this is strongly evident in Southern Bauchi areas, Northern Niger state e.t.c
The hausa dialect spoken by these millions of 2nd language hausa speakers is more of the Zaria dialect (Zazzaganci) & Kano dialect (Kananci).
Infact, the 2nd language hausa speakers in Nigeria (northern minorities) clearly outnumber the native hausa speakers.
This makes hausa the most spoken language in Nigeria.
