First recorded in 1615–25; pre- + disposition
Explanation
A predisposition is a tendency to do something. If you know you have a predisposition toward getting carsick, better to plan ahead and avoid eating before a long drive. Things could get ugly. Predisposition comes from the Latin prae meaning "before," and disponere meaning "put in order, arrange, distribute." If you have a predisposition to think or act a certain way, you can anticipate your reaction before it happens. A genetic predisposition means you are likely to inherit a trait from your parents. Someone might have a genetic predisposition to diabetes or to another illness.
