Modal Verbs: Will, Would & Should

In this lesson you’ll refine how will/would/should express deduction, habit, politeness, and judgement—not just time. Focus on the speaker’s attitude and the implied context.

1 Assumptions and logical conclusions

Used for confident inference about what is probably true in the present or (sometimes) the future, based on evidence or what you know about the situation.

Examples:

• That’ll be John at the door.
• Don’t call her now — she’ll be sleeping.
• You’ll probably recognize him immediately.

Here, will is an epistemic inference (a knowledge-based guess/assumption), rather than volition/decision or future-time reference.

Not the same as a planned future action (I’ll call you tomorrow)—here it means ‘I’m fairly sure.’ Same form, different meaning: if the sentence is about your intention/decision, it’s volitional/future; if it’s based on clues, it’s epistemic (an assumption).

2 Habitual or typical behaviour

Used to describe someone’s characteristic behaviour (often in the present), usually with an attitude such as annoyance, affection, or criticism.

Examples:

• He’ll sit in front of the TV for hours.
• She’ll always complain about something.
• My father will insist on paying for dinner.

This often suggests:

• annoyance
• affection
• criticism
• a ‘knowing’ tone about someone’s typical behaviour

3 Willingness and refusal

Examples:

• The car won’t start.
• He wouldn’t answer my questions.
• She will help anyone in need.

“With wouldn’t/won’t” often imply refusal rather than inability.

With people, won’t/wouldn’t often implies refusal rather than inability. With things (machines/systems), it often means ‘doesn’t work / fails to’. In other contexts, won’t can express a confident negative prediction/assessment (That won’t be enough = ‘I’m sure it isn’t sufficient’).

4 Advanced uses of would

4.1 Past habits

Used for repeated past actions.

Examples:

• Every summer, we would visit my grandparents.
• He would spend hours reading science fiction novels.

Unlike “used to,” “would” is mainly used for repeated actions, not states.

Correct:

• We would play outside every evening.

Incorrect:

• ❌ We would live in Paris.

Soften and specify the constraint: Usually not used for long-term states. Prefer used to or past simple for states.

Prefer:

• We used to live in Paris.
• We lived in Paris (for three years).

Also, ‘would’ for past habits typically works after a past time frame has been established (e.g., ‘When we were kids,…’ ‘Back then,…’). Once the time frame is clear, you can continue using ‘would’ without repeating it in every sentence.

4.2 Politeness and softening

Used to sound less direct.

Examples:

• I would suggest waiting a little longer.
• Would you mind helping me?
• I would imagine that’s quite difficult.

This creates:

• diplomacy
• professional tone
• emotional distance

4.3 Hypothetical attitude

Examples:

• I would never do something like that (in your position).
• She would probably disagree (if you asked her).

Used to express a tentative/imagined stance rather than a firm statement.

5 Advanced uses of should

5.1 Expectation and probability

Examples:

• The train should arrive soon.
• It should be easy to find.
• They should have enough time.

“Should” here means:

probably / expected to

5.2 Emotional criticism or surprise

Examples:

• You really shouldn’t speak to people like that.
• Why should I apologise when I did nothing wrong?
• It’s strange that she should react that way.

At advanced levels, “should” can express:

• irritation
• surprise
• emotional judgement

This is a formal pattern often used after adjectives like strange/odd/surprising/natural (attitudinal should), not advice.

6 Tone and pragmatic meaning

These tones are common interpretations and depend on context, stress/intonation, and relationship between speakers.

Modals often change the emotional tone of a sentence.

Compare: He’ll sit in front of the TV for hours (annoyed) vs He’ll sit in front of the TV for hours (fond/knowing). Meaning is similar, but attitude changes with context and intonation.

Modal	Possible Tone
will	certainty / annoyance
would	politeness / distance
should	expectation / criticism

7 Summary

• will: (1) confident inference about the present (That’ll be John), (2) typical behaviour with attitude (He’ll sit…), (3) refusal/malfunction or strong expectations with won’t.
• would: (1) past repeated actions after a past time frame (When we were kids, we would…), (2) softening/politeness (I would suggest…), (3) hypothetical/imagined stance (I would never…).
• should: (1) expectation/probability (should arrive soon), (2) evaluative/emotional judgement in formal frames (It’s strange that… should…).
• Meaning depends on context, relationship, and tone/intonation; avoid reading these only as tense.
