Tamāyalat comes from the root m-y-l (م ي ل) in Form VI, tafāʿala. The basic verb māla means to incline; tamāyala suggests swaying or yielding in movement. The final feminine marker agrees with the woman as the subject.
The fāʾ connects haṣartu with tamāyalat, showing close succession and an implied cause-and-response relationship. The speaker first describes pulling, then the woman’s movement.
ʿAlayya is a prepositional phrase identifying the direction of the sway: “toward me.” Together, verb form, conjunction, and prepositional phrase construct the moving image.
