obligation
word
Definition
An obligation is something that you must do because of a law, rule, agreement, duty, or moral reason. It can also mean a feeling that you should do something for someone because they helped you or because it is the right thing to do.
Usage & Nuances
Common in formal, legal, workplace, and academic English. Typical patterns are 'have an obligation to', 'legal obligation', 'moral obligation', and 'financial obligations'. It is stronger and more formal than 'responsibility' in many contexts, especially when something is required rather than just expected.
