© 2020 John Wiley & Sons, Ltd.In this paper, kinematics of semi-real quaternionic curve in semi-Euclidean space (Formula presented.) is obtained in terms of its curvature functions. The evolution equation of Frenet frame and curvatures of quaternionic curve are obtained. Also, examples of evolution equations of curvatures are given.
