はず

it should be so

JLPT N4

Meaning and Usage

The Japanese word "はず" expresses a strong expectation or logical conclusion that something should be the case. It is often translated as "should" or "ought to" in English. It implies that based on known facts or reasoning, the speaker believes the event or state is very likely or expected.

Common Contexts

"はず" is frequently used when the speaker is confident about a future event or a current situation due to prior knowledge, promises, or logical deduction. It can be used in both formal and informal contexts but is generally polite when combined with desu/da.

Typical Collocations and Patterns

  • Verb (dictionary form) + はずだ: Expresses expectation that the action will happen.
  • Noun + の + はずだ: Indicates something should be a certain way based on facts.
  • 〜はずがない: Strong negation meaning "there's no way that..."

Nuances and Tips

Using "はず" shows confidence but not absolute certainty. It differs from "でしょう" which is more tentative. Learners often confuse "はず" with "べき" (should/must in a moral sense); remember "はず" is about logical expectation, not obligation.

Example

  • 彼は約束したから、来るはずだ。 (He promised, so he should come.)

This sentence shows how "はず" expresses a logical expectation based on a promise.
