“Ought” and “should” are both auxiliary verbs that are used to express obligation or necessity. They are similar in meaning, but there are a few subtle differences in their usage.
“Ought” is used to indicate a moral or ethical obligation or duty. It is often used to express what is right or correct, especially in a formal or official context. For example:
- You ought to respect your elders.
- The government ought to protect the rights of its citizens.
“Should” is used to indicate a practical obligation or necessity, or to give advice or make a recommendation. It is often used to express what is expected or advisable in a particular situation. For example:
- You should brush your teeth twice a day.
- We should leave early to avoid traffic.
In general, “ought” is more formal and more focused on moral or ethical obligations, while “should” is more casual and more focused on practical considerations. However, both words can be used in a variety of contexts and can overlap in meaning in some cases.
