Tecnically it is more like the essence of the other as an outside to the self.
so the tion or ation(depending on which century) would be process of the outside self of other.
dura (the other or third person, the not the self, the un-self) process(tion), movement
movement is probably more so an association rather than a discription.
our essence of movement is more a translational aspect of the process
like the word "motor"
"flow" would be quite similar though emotional association trends to quantify a volumetric reference
the movement can not flow
the flow IS the movement.
does the movement have flow ? that is an intrinsicly different question based on a supposition of agreed meaning.
thus a directional aspect of nature is already accepted.
is the type of flow duration ?
yes
how can that be ?
because time is the factor. not movement.
