This question came from our site for linguists, etymologists, and serious English language enthusiasts.

  • @Colleen The site is called "English for Language learners", if someone is proficient in English they wouldn't be asking this type of question in the first place. Preferring to revert back to the ungrammatical question (Why would is used here?) when the correction is one of the most basic rules in English. So, learners see a post that has been edited by a user with 6K and think "This must be grammatically acceptable". – Mari-Lou A Jun 4 '16 at 17:06
  • @Mari-LouA Answers should be edited for grammar and style, questions should not unless it is impossible to decipher what the author meant. Learners know that learners are asking the questions. Obscuring the learner's proficiency not only may net them answers with language too difficult to understand, it may put off other learners when they see the perfect English of the questions. meta.ell.stackexchange.com/q/2769/9161 – ColleenV Jun 4 '16 at 22:55
  • @ColleenV if the question had been in perfect English, I might agree. There were enough clues that it wasn't. – Mari-Lou A Jun 4 '16 at 23:24
  • @Mari-LouA This discussion really belongs on meta and not under this question. I acted according to what I believed was the community consensus based on what we've discussed on meta. – ColleenV Jun 4 '16 at 23:30

Would has a simple, non-modal use as the past tense of will. You can see this when tenses get backshifted in indirect discourse. The direct speech

He said, "I will go."

becomes

He said that he would go.

But the word also has a host of modal uses, that is, uses that reflect different aspects of meaning beyond person, time, and number. These are largely idiomatic, which means that they are not amenable to analysis. They have just become fixed in the language over the course of the millennium that the the word has been in the language. Here are a few usages:

  • Willingness: They asked us whether we would join them for dinner.
  • Consent: If you would only stop talking, I will explain.
  • Preference: I would rather not. I would love to come to the party.
  • Accustomed to: He would often come home drunk.
  • Capability: I thought I had the right key, but it would not work.
  • Persistence: I told him to stop, but he would not be deterred.
  • Determination: Be wary of those who would impose their tastes on others.
  • Intention (when backshifted in indirect discourse): He said, "I will pay the bill myself" -> He said that he would pay the bill himself. (In the conclusion matching a conditional subjunctive): If you were to ask me, I would say no.
  • Inevitability, compulsion (as an alternative to should): I would know that face anywhere.
  • Refusal (in the negative): No matter what Obama proposed, the Republicans would have none of it.
  • Desire (with subject-verb inversion): Would that God grant my prayers.
  • In an expression of a wish, as the verb in the clausal object: I hoped that he would arrive today.
  • Past report of future action: The Puritan's chief concern was that somebody, somewhere would enjoy himself.
  • Present indirect report of future action: He said, "I will go." -> He said that he would go.
  • In 2nd and 3rd person indirect discourse, as a substitute for 1st person should: I said, "I should have the report for you tomorrow" -> He said that he would have the report tomorrow
  • Emphasis In rhetorical questions: Who would have thought her capable of murder?
  • Presumption or probable past state: They were in the same class, so they would have know each other.
  • Necessity: He grew so angry, it seemed he would explode.
  • Uncertainty: So it would seem. So I would think.
  • Softening of a declarative statement: I think that he has stopped gambling -> I would think that he has stopped gambling.
  • Softening of an imperative statement: Will you set the table -> Would you set the table.
  • Expressing possibility in the conclusion matching a conditional subjunctive: If he weren't a biter, then your kid would be in daycare.
  • Expressing advice in the conclusion matching a conditional subjunctive, which might be understood but not stated: I wouldn't do that [if I were you].

It is not an easy question to answer and would as a modal verb has a lot of meanings. You would need to look up the dictionary and get yourself familiarized with all those definitions and usage examples. In your example, it means No. 5 in the link:

Expressing a conjecture, opinion, or hope

The main difference between "you have to do that" and "you would have to do that" is the latter is more polite and less strong in terms of requesting the other party (you) to do that. In other words, the latter shows less conviction of the speaker in terms of why the action should be done. The latter could be rephrased to:

I think you have to do that. In my opinion, you have to do that.

Would also could be used to express a desire or polite request. It will largely depend on the context.

  • I agree with the above answer. I would also like to add that some linguists claim that "would" is the past tense version of "will" but don't ask me to explain because I forgot why this is the case. The same goes for "should" and "could" being the past tense versions of "shall" and "can" . – Danny Rodriguez Apr 18 '16 at 8:36
  • @DannyRodriguez I can see what you mean by your comment. The thing is would, could, and should are all past forms of will, can and shall. However, it evolved to mean many different things without tense aspect ans I think that's why grammarians started to classify them as a modal verb. – user24743 Apr 18 '16 at 8:43
