Should vs. Would How to Choose the Right Word

The words should and would are both  helping verbs (in particular,  modal auxiliaries), but they dont mean the same thing.  Should and would are two of the 10 modal verbs in English (the others are can, could, may, might, must, ought, shall, and will). A  modal is a  verb  that combines with another verb to indicate  mood  or  tense. Should  is actually the  past tense  of another of these modal verbs, shall.  Used as an auxiliary, should  expresses a condition, an obligation, futurity, or probability. Would  is the past tense of the modal verb will.  Used as an auxiliary, would expresses a possibility, an intention, a desire, a custom, or a request. Use should to express an obligation, a necessity, or a prediction; use would to express a wish or a customary action. How to Use Should Use should to express something that is probable, ask a question, or show an obligation or give a recommendation. To express something that is probable, you might say, Joe should be here soon. To ask a question using should, you could say, Should I dress formally for the dance? And, to make a strong recommendation, you might say, You should stop eating so much, or youll soon gain weight. How to Use Would Use would to make a polite request, ask questions, or express something about hypothetical situations. So, to make a polite request using would, you could say, Would you please pass the jelly? To ask a question using this term, you could write, Would you like ketchup with your fries? And, to express a hypothetical sentiment, you might state, If I won the lottery tomorrow, I would quit my job and retire the next day. Examples To use should to express an obligation, you could state: We should try to be more patient with one another. In this example, should expresses something that we (the subject of the sentence) ought to do. The term, would, by contrast, often is used to express a customary action, as in this example: When Joe was younger, he would often take the long way home after school. In this sentence, would expresses a habit or custom that Joe practiced when he was young: that he often took the long way home. Should can also be used to express different degrees of certainty or obligation, which makes mastering this modal verb tricky. For example, consider the modal verb  should go  and how its used in the following two sentences: The bank closes in 15 minutes. We should go there now.Joe should go to the bank only if he needs to get cash. The first example expresses a definite degree of certainty: The bank closes in 15 minutes and, therefore, we need to go right now and get there before closing time. The second sentence expresses a lower degree of certainty: Joe should go to get cash only if needs cash. In other words, if Joe does not need cash, he should not go to the bank. How to Remember the Difference Use should to say that something is the right thing to do; use would to talk about a situation that is possible or imagined. So, add another modal, such as could, to the sentence to see if it still makes sense. For example, you could say: Joe should call his mom this week. This means that Joe ought to call his mom; its the right thing to do. If you add the word could, the sentence doesnt make sense: Joe should call his mom this week if he could. That sentence doesnt work because Joes obligation to call his mom has nothing to do with whether he could (is able to) call her. Its still his obligation and the right thing to do. But, if you were to say: Joe would call his mom if he were able to do so. Youre talking about a situation that is possible or imagined; Joe would call his mom, but due to circumstances, he may not be able to do so. You could add the phrase if he could to the sentence and it would still make sense: Joe would call his mom if he could. Another way to think of it is should is solid—it is something that ought to happen. Would is wobbly—its something that might happen but probably wont. British vs. American Usage As noted, in general usage, should implies an obligation or something that ought to be done, and would implies something that is possible. However, in formal British English, there is an alternative use for should, which reverses its meaning compared to American English. In formal British English, a person might say: I should like a cup of tea before I go to bed. In this case, should does not mean a sense of obligation or something that ought to happen. Used as such, its meaning is closer to the word would, as in something that is possible. Indeed, in American Engish, a speaker would say or a writer would write: I would like a cup of tea before I go to bed. This means that being given a cup of tea is something that might happen, but it might not, This, then, is actually the meaning a person is conveying if she is using formal British English.
