<div class="pullquote">

**でしょう** means **probably or right**. It is a **JLPT N5** Japanese grammar pattern used to make a polite guess or ask for agreement.

</div>

This grammar point appears often in beginner conversations, textbooks, and JLPT-style reading questions. If you want to sound less certain and more polite when predicting something, **でしょう** is a useful pattern to learn early because it connects directly to everyday communication.

## What does でしょう mean?

Use **でしょう** when you want to express probability or invite agreement in polite Japanese.

Natural translations include:
- probably
- I suppose
- right?

The exact English translation changes with context. The important point is to understand what job the pattern is doing in the sentence, not to memorize only one English phrase.

## How to form でしょう

<div class="formation">

<div class="formula">
<span class="ftoken t-stem">Plain form</span>
<span class="fplus">+</span>
<span class="ftoken t-core">でしょう</span>
</div>

<div class="formula">
<span class="ftoken t-stem">Noun / な-adjective</span>
<span class="fplus">+</span>
<span class="ftoken t-core">でしょう</span>
</div>

</div>

Examples of the pattern:
- <ruby>雨<rt>あめ</rt></ruby>が<ruby>降<rt>ふ</rt></ruby>るでしょう
- <ruby>便利<rt>べんり</rt></ruby>でしょう
- <ruby>先生<rt>せんせい</rt></ruby>でしょう

Pay attention to the form that comes before the grammar point. Many beginner mistakes happen because the learner understands the meaning but attaches the pattern to the wrong word form.

## When is でしょう used?

Use **でしょう** in situations like:
- weather forecasts
- polite guesses
- confirmation questions

Tone and register:
- polite and neutral
- Common in daily speech, textbook examples, and beginner JLPT questions

<p class="example-en">She has probably already arrived at the station.</p>
<p class="example-foot"><span class="example-tag">probability</span></p>

<p class="example-en">This kanji is difficult, right?</p>
<p class="example-foot"><span class="example-tag">agreement</span></p>

<p class="example-en">There will probably be many people on the weekend.</p>
<p class="example-foot"><span class="example-tag">probability</span></p>
</div>

<div class="example">
<p class="example-jp">これは<ruby>便利<rt>べんり</rt></ruby>でしょう？</p>
<p class="example-en">This is convenient, right?</p>
<p class="example-foot"><span class="example-tag">agreement</span></p>
</div>

</div>

Read the Japanese sentence first, then check whether the English translation matches the feeling of the whole sentence. This helps you avoid translating each piece too literally.

## Nuance of でしょう

The key nuance is **polite probability or shared expectation**.

This matters because learners often know the dictionary meaning but miss the speaker's intention. In real Japanese, grammar points show attitude, politeness, contrast, certainty, desire, or context. For **でしょう**, focus on how the pattern changes the role of the sentence.

For example:
- In conversation, it can sound softer and safer than blunt certainty.
- Compared with **だろう**, it feels more polite and less rough.

<strong>Speaker intention:</strong> In real Japanese, grammar points show attitude, politeness, contrast, certainty, desire, or context. For <strong>でしょう</strong>, focus on how the pattern changes the role of the sentence.

## でしょう vs だろう

Both **でしょう** and **だろう** can be related in beginner Japanese, but they are different.

<div class="compare">

<div class="cmp a">
<p class="cmp-head">でしょう</p>
<p class="cmp-sub">polite form used with many listeners</p>
<p class="cmp-when">common in forecasts and explanations</p>
<p class="cmp-eg"><ruby>明日<rt>あした</rt></ruby>は<ruby>寒<rt>さむ</rt></ruby>いでしょう。</p>
<p class="cmp-eg-en">Tomorrow will probably be cold.</p>
</div>

<div class="vs">vs</div>

<div class="cmp b">
<p class="cmp-head"><a href="/blog/n5-darou/">だろう</a></p>
<p class="cmp-sub">casual/plain counterpart</p>
<p class="cmp-when">can sound masculine or literary depending on context</p>
<p class="cmp-eg"><ruby>明日<rt>あした</rt></ruby>は<ruby>寒<rt>さむ</rt></ruby>いだろう。</p>
<p class="cmp-eg-en">Tomorrow will probably be cold.</p>
</div>

</div>

If you are unsure which one to use, ask what the sentence is trying to do: define something, ask something, show a reason, mark a subject, describe a desire, or connect ideas.

<div class="mline-body"><span class="good">この<ruby>漢字<rt>かんじ</rt></ruby>は<ruby>難<rt>むずか</rt></ruby>しいでしょう？</span></div>
</div>
</div>

A good study habit is to make one simple original sentence, then change only one part of it. That makes the function of the grammar point easier to see.

## Is でしょう on the JLPT?

<div class="jlpt-card">
<div class="jlpt-shield">N5</div>
<div class="jlpt-info">
<p>Yes. <strong>でしょう</strong> is commonly taught as <strong>JLPT N5</strong> grammar.</p>
<div class="jlpt-checks">
<ul>
<li>Recognize it in reading and listening</li>
<li>Understand its nuance in context</li>
<li>Use it in simple original sentences</li>
</ul>
</div>
</div>
</div>

For test preparation, do not only memorize the English gloss. Practice identifying the word before and after the grammar point, because JLPT questions often test structure and context together.

## Practice questions for でしょう

<div class="prompts">

<div class="prompt">
<span class="prompt-num">1</span>
<span class="prompt-text">Make a polite weather prediction using <strong>でしょう</strong>.</span>
<span class="prompt-tag">production</span>
</div>

<div class="prompt">
<span class="prompt-num">2</span>
<span class="prompt-text">Ask “It is convenient, right?” with <strong>でしょう</strong>.</span>

<span class="prompt-num">3</span>
<span class="prompt-text">Guess that a friend is busy using <strong>でしょう</strong>.</span>
<span class="prompt-tag">production</span>
</div>

</div>

Keep the sentences short at first. Once the form feels natural, add time words, places, reasons, or contrast to make the sentence more realistic.
