Difference Between 'Should' and 'Ought To' as Modal Verbs of Obligation



Hello, Sophie!
That is a great question! Should" and "ought to" both express advice or obligation, but they differ slightly:
- Formality:
- Should is more common and casual.
- Ought to is more formal and less used in daily conversation.
- Strength:
- Ought to can feel stronger, implying moral duty.
- Negative form:
- Shouldn't is common.
- Ought not to is formal and rare.
Examples:
- You should study more.
- You ought to be more careful.
I hope this helps!
