The words should and would are both helping verbs (in particular, modal auxiliaries), but they don't mean the same thing.


Should is the past form of the verb shall. Used as an auxiliary, should expresses a condition, an obligation, futurity, or probability.

Would is the past form of the verb will. Used as an auxiliary, will expresses a possibility, an intention, a desire, a custom, or a request.

Put simply, use should to express an obligation, a necessity, or a prediction; use would to express a wish or a customary action.

  • "The fog has lifted enough for us to see the place where the sun should be, and it's brighter yet out by the Golden Gate and we take the little boat out and aim for the brightness, the way a real couple might on a Saturday afternoon."

    Usage Notes

    • Uses of Should and Would in British and American English
      "[W]ould is now almost invariably used for expressing the future-in-past for all three persons, according to Longman Grammar (1999) research. For example:
      I said I would expect to come.
      You said you would expect to come.
      They said they would expect to come.
      Should serves to express prediction/volition instead of would only in deferential style. Compare:
      I should like to come. I would like to come.
      I should be delighted. I would be delighted.
      This rather formal style is much more British than American. Comparative data . . . show that its use is seven times more frequent in the UK than the US. . . .

      "Other uses of should make it a modal verb of obligation and necessity, whereas would continues to express volition and/or future possibilities . . .."
      (Pam Peters, The Cambridge Guide to English Usage. Cambridge University Press, 2004)
    • Should, Would, and Should/Would
      "There are really three different verbs: should, would, and the mixed verb should/would.
      1. should
      This verb ( I should, you should, he/she/it should etc.) is used to talk about obligation, and in some other ways.
      Everybody should wear car seat belts.
      She should be back tomorrow.

      2. would
      This verb ( I would, you would, he/she/it would etc.) can be used to talk about past habits.
      When we were kids we would spend hours kicking a ball about, dreaming of being soccer internationals.

      3. should/would
      This verb—often considered as a 'conditional auxiliary'—has mixed forms: I should/would, you would, he/she/it would, we should/would, they would. In general, should/would is used as a past form, or less definite form, of shall/will. It is common in requests, offers and sentences with if.
      I told them we should/would probably be late.
      I should/would be grateful for an early reply.
