Ok, then what exactly is "yaw"? My understanding is that it is a change
of direction of the longitudinal axis of the aircraft in the plane that
is roughly coplanar with the wings.

Yaw, as we define the term in flight test as it relates to directional
stability is defined as moments about the VERTICAL axis, not the
longitudinal axis. These moments also relate to Yaw Angle, Yaw Rate, and
Sideslip Angle.
