What is Have To?

When we express something necessary, we use ‘have to.’ It concerns general obligations. When discussing another person’s responsibility, we use ‘have to.’ Have to mean showing a kind of compulsion thing strongly.

It’s not an auxiliary verb because it uses ‘have’ as the main verb. It’s grouped with modal auxiliary verbs for convenience most of the time. Also, it’s not a modal verb, of course. The structure goes like this with a subject, an auxiliary verb, then using have, a then to-infinitive.

The usage is wide in case of having to. It can be used to say that the law needs something. To show some direction or abide by something. For example,” People have to wear a mask when they come out on the road” it’s a needful thing. Or like,” All passengers must exit at the next station”.

If we talk more about having to, we will realize that it can also be used to show desire or something to be executed. For example, “You have to taste this dessert. It’s mouth-watering” expresses an emotion, a desire to let them taste the dessert. Or like,” You have to read this novel; it’s impeccable”.

What is Should?

Should is an auxiliary verb. It is a modal auxiliary verb, to be specific. Its primary use is to give advice, talk about obligations, probability and expectations, and replace a subjunctive method, expressing a mood based on some conditions.

When you convey your view or the right thing about something, you use should. The word should express something right and correct to someone to do or entertain something or for an event to occur. The implementation part also extends to suggest someone about something.

If we talk about the pseudo subjunctive, its primary use is to let know that event or happening that somebody wants to happen and hopes to become true. For example, “The head of the team wants me that I should join the team”. This insisting way is quite a sure thing in case of should.

Taking conditional statements, it could be used as in “If I went outside without a mask, I should catch a disease”. This reveals that if the first part doesn’t get executed, the second part will come true.
