trastorno
/tɾasˈtoɾno/ · B2 · noun · m
disorder
🌀 tras + torno = behind the lathe turn, a thing knocked off its turning course
Trastorno comes from trastornar, from tras- (over, across) + tornar (to turn). Something turned over or upset is a disturbance or disorder. Link torno (lathe, turning) with tornado: both involve turning out of order.
