(Region of Kande, Lama, Benin, Ghana; Niger-Congo, Gur)

To account for the alternations between the segments of the root and those of the progressive suffix ku in CVm roots, Ourso (1989) introduces a metathesis rule.
hom ---> 'pull' ---> i hoo~ ---> 's/he is pulling'
nam ---> 'grind' ---> i no^o~ ---> 's/he is grinding'
kpem ---> 'go home' ---> i kpo^o~ ---> 's/he is going home'

Metathesis rule (Ourso, 1989): CVm-u(1 2 3 4) ---> CVum (1 2 4 3)
