ramification
A result or effect that comes from a decision or action.
A ramification is a consequence or result that branches out from a decision or action, often in ways you didn't expect. The word comes from how tree branches split and spread: one choice can lead to many different outcomes, just like one branch splits into many smaller branches.
When your school decides to change the lunch schedule, the ramifications might include longer lines, happier students who can eat with friends from different grades, and teachers adjusting their lesson plans. When a city builds a new highway, the ramifications spread far beyond just having a new road: property values change, businesses open or close, and traffic patterns shift throughout the region.
Usually, we talk about ramifications when discussing important decisions. Before a company launches a new product, they try to predict all the ramifications: Will customers like it? Will it hurt sales of their other products? Will competitors copy the idea? Smart decision-makers try to think through the ramifications before acting, though it's impossible to predict every outcome.
The word almost always appears in plural form (ramifications not ramification), because significant choices rarely produce just one consequence. The effects multiply and extend in various directions, each creating its own set of results.
