Presumption
Definition 1 of 4
Pro Tip 1/2
Likelihood and Assumption
Use 'presumption' when you believe something will likely happen without solid proof. There's a general presumption that the new policy will benefit students.
Pro Tip 2/2
Not a Certainty
'Presumption' suggests a strong belief, but remember, it's not a fact or guarantee. Despite my presumption of good weather, it rained during our field trip.
