'Should' is a modal verb used to make recommendations or give advice. It can also be used to express obligation.

'Should' is a modal verb that is used for:
- giving advice, suggestion or recommendation

Ought to and Should
Sometimes 'should' is replaced by the modal verb 'ought to'. 'Ought to' is more formal and it is not used very commonly in spoken English.
Advising Not to Do Something
By using the negative form of 'should' i.e. 'shouldn't' or 'should not' you can advise somebody NOT to do something.
Do NOT use phrases like 'I think...' or 'I believe...' with the negative form of 'should.
More commonly in English, they make the verb 'think' or 'believe' negative.
I don't think you
shouldn't eat too much candy.)
'Should + But'
There is a special structure in the English grammar made by the modal verb 'should.' In this case, first a background sentence is expressed followed by one of the interrogatives (what, who) that is put before 'should' then we use the term 'but' before the phrase which makes us shocked the most.
Take a look at examples.
I went to the party and what
I was having fun, and who
'Shall' and 'Should' are used as modal verbs. They have many functions as were discussed in the article. So, let us take a look at some more examples to be clarified.
