Required by duty, law, or a promise to do something.
“The company is obligated to notify customers of any price changes in advance.”
“Tenants are obligated to give thirty days' notice before moving out.”
This word appears in letters describing responsibilities, such as 'the landlord is obligated to make repairs.' Understanding it helps you distinguish an obligation (something someone must do) from a permission (something someone is allowed to do) in rule-based reading questions.
Synonyms: required, bound, compelled
