Will, Would & Shall

Three modal verbs — will, would and shall — handle the future, polite requests, and imagined situations. They're closely related, which is both good news and bad news: good, because learning them together shows how they connect; bad, because they're easy to muddle. Will feels straightforward until you notice it does several different jobs. Would looks like a past-tense word but often isn't about the past at all. And shall sounds old-fashioned until you realise you probably use it every day in "Shall we…?" Let's take them one at a time and see what each is really for.

will

Will is the busy one. Its main jobs are:

• Future prediction or decision: It will rain. I*'ll** help you.*
• Willingness and promises: I will always remember this.
• Refusal (won't): The door won't open.

That last job surprises people. "The door won't open" isn't really about the future — it's the door refusing to open, right now. So will isn't only a "future" word; it also carries the idea of willingness or, in the negative, flat refusal.

would

Would is the softer, more distant cousin of will. It does three neat jobs:

• Polite requests: Would you help me, please?
• Imagined situations: If I won the lottery, I would travel the world.
• Past habits: When I was small, we would visit my gran every week.

Notice that only the third job is really about the past. In the first two, would isn't a past-tense word at all — it's doing politeness and imagination. That's the thing to watch: would looks past-y but usually isn't.

shall

Shall is more formal and mostly British. Its two everyday jobs are:

• Offers and suggestions (with I / we): Shall I open the window? Shall we go?
• Old-fashioned future: I shall return.

In modern English, will has mostly taken over from shall for talking about the future — you rarely need "I shall" any more. But "Shall I…?" and "Shall we…?" are still alive and useful, and you'll hear them constantly whenever someone offers to do something or suggests doing it together.

A second angle: who does the action?

Here's a test that clears up a lot of confusion between these words: ask who is expected to do the thing? "Shall I get the chairs?" offers your help — you'll do it. "Would you get the chairs?" asks the other person to do it — they'll do it. Get those the wrong way round and a polite offer accidentally turns into an order, or the other way about. So before you choose, picture who ends up doing the work: Shall I…? points at yourself; Will you…? / Would you…? points at someone else.

Watch out — would for politeness

Would is your best tool for making a request gentler and more polite:

Will you pass the salt? → Would you pass the salt, please? (more polite)

The softer, more distant feel of would is exactly what makes it sound courteous. That's why it's the word to reach for when you're asking a favour of a teacher or an adult you don't know well.

More worked examples

• ✓ Tomorrow will be sunny. (a prediction about the future)
• ✓ If I were braver, I would audition for the play. (an imagined situation)
• ✓ Every summer we would camp by the sea. (a past habit — repeated actions)
• ✓ Shall I carry that for you? (an offer — I'll do it)
• ✗ Shall you help me? → ✓ Will you help me? / Would you help me? ("shall you" isn't natural)

An edge case: "would" for the past, "will" for now

Here's a pairing that catches students out because the two look so similar. Will and would can both describe habits — repeated things people do — but one is for now and one is for then. Will sketches what someone characteristically does these days: "She'll spend hours drawing" means that's just what she does. Would does the same job for the past: "She would spend hours drawing when she was younger" means that's what she used to do. So the leap from will to would here is really a leap in time, from a present habit to a past one. And there's one limit worth remembering: this past-habit would only works for actions you repeated, not for states. You can say "we would visit the seaside every year" (an action), but not "I would have long hair" to mean you used to — for a state like that, English wants used to instead. Keep would for the things you did, and you'll stay on safe ground.

Why it matters

These three words are how you sound confident, polite, or imaginative exactly when you mean to. In a story, would lets you paint the past — "every winter the pond would freeze" — with a warm, once-upon-a-time feel that plain past tense can't quite manage. In real life, swapping a blunt "Give me the pen" for "Would you pass me the pen, please?" is the difference between rude and polite, and adults notice it instantly. And knowing that "Shall I…?" offers your own help while "Would you…?" asks for someone else's keeps your meaning crystal clear, so a friendly offer never comes out sounding like a command. Small words, big effect on how you come across.
