Structure Of Should

Should have a great significance in English Grammar, it is a modal verb that is used with the base form of the verb. We use the verb “should” when we stating what would be the right thing to do or the right state for something to be in. For instance, you should complete your work on time. 

There is another modal verb called “must.” For instance, you might do your homework on time. 

Here, the difference between the verb should and must is, while using should in a statement, we don’t put compulsion on someone to do something, which means the second person has the choice to do it or not. It is just like giving suggestions to someone or advise with politeness. However, must is a verb that is used when you are emphasising on someone to do something. It is just like a piece of string advice with compulsion or less politeness.
