sufficient condition
Alone implies result
A sufficient condition is something that, if present, guarantees a particular outcome or makes something else true.
Having oxygen is not a sufficient condition for fire—you also need fuel and heat—but the presence of all three together is sufficient.
The term appears frequently in logic, philosophy, and scientific reasoning, often paired with its counterpart necessary condition, which must be present but alone may not guarantee the result.
