dynamic = "influencing circumstance(s)"?

[victor steinbok]

"Dynamics" as "interactions" that may include "circumstances" is used rather
heavily--if for no other reason, because *I* use it when the dynamics of a
conversation call for it. ;-) (e.g., "The dynamics of the situation warrant
intervention.") Not sure about "dynamic". I am still trying to sort out
"ethic" vs. "ethics"--but this one goes back centuries.
