Obligation and advice: the pressure dial

PRESSURE DIAL
↑ more pressure / less choice

BLOCKED: must not = no permission
  You must not park here.

RULE / NECESSITY: have to / need to / must
  You have to wear a helmet on the site.

WARNING: had better = strong advice + risk

ADVICE / EXPECTED RESULT: should / ought to
  You should take a jacket.
  The package should arrive tomorrow.

NO NEED: don't have to / don't need to
  You don't have to answer every question.

Key negative contrast:
  don't have to = no need
  must not = no permission
↓ less pressure / more choice

Choose the helper by how much pressure there is: no need, good idea, warning, rule, or blocked action.

Introduction

Choice, pressure, and advice

Obligation and advice tell the listener how much choice there is. English does not use one word for every situation. Use have to or must when something is required, and use need to when something is necessary for a result. Use should or ought to for advice, and use had better for urgent advice with a warning feeling. The main action stays in its base form inside these frames: You have to wear a helmet on the site. You should take a jacket.

Cognitive metaphor

A pressure dial

Think of these expressions as a pressure dial. Must and have to are high pressure: a rule, duty, or strong demand leaves little choice. Need to is also strong, but the pressure comes from a goal or practical result. Should and ought to are middle pressure: they point to the best, fairest, or expected path. Had better is a warning light: the choice still exists, but ignoring the advice may cause a problem soon.
Core pattern

Core frames

Build the sentence around a fixed frame. Have to and need to change with the subject: I have to, she has to, we need to, he needs to. Must, should, ought to, and had better do not take -s. The main action stays plain: She has to work late tonight. Questions with have to and need to use do: Do we have to pay now? Does he need to bring ID? Questions with should do not use do: Should I call him now? Do not add -s to the main verb: not She has to works.
Core व्याकरण A2 शब्दसंग्रह A2 Neutral

Contrast

Must, have to, and need to

Must and have to are the closest common confusion. Both can mean obligation, but have to is the normal everyday choice for outside facts, arrangements, and duties: I have to get up at six for work. Must often sounds stronger, more personal, or more official: Visitors must sign in. Need to focuses on necessity for a purpose, not authority: We need to charge the laptop before the meeting. Must I sign both copies? is correct but formal or serious. Do I have to sign both copies? is more common.

Usage rules

Negatives: no need or no permission

Negative forms change the meaning sharply. Don't have to and don't need to mean there is no necessity; the action is optional. You don't have to answer every question. He doesn't need to come to the meeting. Needn't has the same no-necessity meaning, but it is less common or more formal in everyday speech. Must not or mustn't means prohibition: You must not park here. Shouldn't means advice not to do something: You shouldn't text while driving. Do not confuse no necessity with no permission. If parking is forbidden, You don't have to park here is the wrong message; it means parking here is not required.

Contrast

Should and ought to

Should is the normal verb for advice. Ought to means almost the same thing, but it is less common and can sound a little formal or moral: You ought to apologize. Use should + base verb, but ought to + base verb. The negative shouldn't is common; ought not to is correct but less frequent. Questions with should are normal, while question forms with ought to are formal. Should and ought to can also express expectation, not advice: The package should arrive tomorrow. She ought to be home by now.

Danger zone

Had better is a warning

Had better + base verb gives urgent advice with a possible bad result if it is ignored. It is usually about a specific situation now or soon, not a general habit: You'd better save the file now. The negative is had better not: You'd better not be late. The had is often shortened to 'd and does not make the meaning past. Do not add to after better. Wrong: You had better to save the file now. Correct: You had better save the file now. Questions with had better are uncommon; use should when you simply want advice.
Summary

Function map

Choose the expression by function. For strong obligation, use have to for most everyday duties and must for strong, official, or strongly stressed rules. For practical necessity, use need to. For no necessity, use don't have to or don't need to. For prohibition, use must not, can't, or not allowed to. For advice or expectation, use should; choose ought to when a slightly formal tone is acceptable. For urgent warning advice, use had better, especially with I, we, or close relationships.
