In this article we investigate some classes of meromorphic or complex harmonic functions with a pole, which are generated either by analytic conditions or by “coefficient inequalities”. There are given theorems, which combine the geometrical properties of functions of the introduced classes. Some results broaden knowledge about the classes of functions, which were investigated in [
