About はずだ

はず, coming from the kanji (はず), is a word in Japanese that is very similar to 'bound' in English. This means that it expresses something that the speaker is 'quite sure is true', but cannot confirm. The most common translations of はず are 'bound to be (A)', and 'should be (A)'.
As はず is a noun, it may be used in any place that a noun would usually be used. It will often be followed by , or です.
  • 今日(きょう)(あめ)()はず
    It is supposed to rain today. (But I am not 100% sure if it will)
  • 新幹線(しんかんせん)()(ほう)(はや)はず
    It is bound to be faster if we go by shinkansen. (But I am not 100% sure if it will)
  • (かれ)(さかな)(きら)から寿司(すし)(きら)はず
    He does not like fish, so he is sure to dislike sushi. (But I am not 100% sure if he will)
  • (たの)のはコーヒーはずだったけど(ちゃ)()
    I was sure that I ordered coffee, but tea came. (But I am not 100% sure if I did)
Despite はず sometimes being translated as 'should', this is only when you think that something 'should be true', and cannot be used when making suggestions/giving advice. Due to this, 'bound' is the more accurate translation of (はず), in almost all situations.
Fun Fact
The (or です) in はずだ may be omitted. This usually makes はず sound a little less certain, like 'bound to be (A)... probably'. In the same way, speakers may sometimes add はず to the end of their sentences in a similar way to 多分(たぶん), in order to show that they are not 100% certain about whether what they just said is accurate or not.
  • ハリー今日(きょう)パーティー()く…はず
    Harry will go to the party today… Probably.
  • ()かけ(まえ)(いえ)(なか)電気(でんき)全部(ぜんぶ)()はず
    I turned off all the lights in my house before I left… I'm pretty sure.

    According to the great suggestion, I have added the information to the grammar point!


    Sorry for late answer (basically I have been sick for last few weeks )

    Perhaps the grammar point should just be はず? In the examples used in Genki it uses はずです and the DBJG item is just はず giving examples that use both だ and です.

    The structure section could be rephrased as はず + ( だ/です)

    There is a Japanese Ammo video for this.
