Modal Verbs (Suggest & Advise)

The modal verb OUGHT TO is similar to should.

We use it for formal and serious things: professional suggestions or advice, for example.

“The urgency of the situation ought to have been considered earlier.”

Ought to and should are usually interchangeable. Ought to is appropriate for formal situations and does not sound as direct as should.

Ought to is probably the least used of all the modal verbs, but it still has a place in everyday English.
