The is a certain way of talking where you can end just about anything you say in わけ.

What is the sentence structure for this way of talking?

While sawa's answer does cover the basic construction rules, it's definitely worth it to go over the different use cases of わけ. Grab a comfy chair and your favorite beverage, because this is a long one.

The best and most complete analysis I've found of this use of わけ is in this 2001 paper by Atsuko Yokota:

It's freely available as a PDF (yay!) but it's entirely in Japanese (hrm), so the best I can give you here is a summary of the five (yes, five) distinct uses of わけだ which Yokota lists.

## Yokota's Differentiation of わけだ

Diagrammatically, Yokota charts out the first four uses of わけだ in her paper. Here is a clarified and prettified version:

### 1. Marks a logical conclusion or result based on some known fact

The common thread in this type of sentence is that a known fact Y is used as the logical basis for a conclusion Z:

Y (known): The water is really rough today, isn't it?

Z (conclusion): As a result, will we not be able to put out to sea today?

Y (known): The time difference is four hours, so

Z (conclusion): based on this we'll arrive right at noon Japan time.

Y (known): When I weighed myself I was at 52 kilos. Last week I was 49 kilos, so

Z (conclusion): this means I gained a whole three kilos in one week.

### 2. Marks a reason or cause for some matter

This is like the first use, only in the opposite direction. We take some known fact Y, and use わけ to mark X, the reason for or cause of Y:

Y (known): It's quiet in the school, isn't it?

X (reason): Ah, it's because we're in winter break now, right?

Y (known): This year's rice crop was poor.

X (reason): This is due to the cool summer we had.

Y (known): See how the water is really rough?

X (reason): It's because there's a typhoon approaching.

### 3. Marks the speaker's acceptance/acknowledgement of some truth

This is a little more complicated than the first two uses. Essentially, we again start with some known fact Y (which may be unspoken). An answer for why Y is true is presented as X, and this leads to the conclusion that X naturally yields Y:

フランスで中学【ちゅうがく】まで行【い】かれたのですか。道理【どうり】で、フランス語【ご】が流暢【りゅうちょう】なわけですね。

Y (known, unspoken): You are fluent in French.

X (why is Y true?): You were in France through junior high?

Y (acknowledged): No wonder you're fluent in French. (acknowledging that X naturally yields Y)

あかないわけです。かぎが違【ちが】っているのですから。

Y (known): It won't open. (Listener: Why not?)

X (why is Y true?): The keys are different. (Listener: Ah, so that's why.)

Y (known by wife, unspoken): Mr. Suzuki is at home even during the middle of the day on weekdays.

X (why is Y true?): Husband: I heard that Mr. Suzuki next door resigned from his job.

Y (acknowledged): Wife: Ah, so that's why he's at home even during the middle of the day on weekdays.

### 4. Marks a restatement of some fact

This is one of the simplest uses of わけ. Here, a known fact Y is restated or presented from a different angle as Yʹ. Often you'll find this use of わけ paired with つまり:

Y: Her father is my mother's younger brother.

Yʹ: In other words, she and I are cousins.

Y: Mr. Yamada got a job at the South Korean consulate.

Yʹ: Essentially, he's moved up in the world.

### 5. Does something entirely untranslatable

Unfortunately, there has to be a catch-all category, since わけ gets used kind of like a sentence-final particle without any significant effect on the meaning of the sentence. Even Yokota admits that "speakers often use [わけ in this way] unconsciously."

こうして二人【ふたり】は結婚【けっこん】して、幸【しあわ】せに暮【く】らしたわけです。

And so the two married and lived happily.

This わけ doesn't fit nicely into any of the four preceding categories. You might think it falls under #1 (a conclusion based on some known fact), but this sentence isn't a conclusion of anything; it's merely a statement of some known fact, without any connection. We could, in fact, remove わけ entirely, without affecting the meaning, by replacing 暮【く】らしたわけです with 暮【く】らしました.

Inside this category is the use of わけ to set up a context or prologue for a succeeding statement. We find ～のだ being used in a similar way:

わたしは国史【こくし】を専門【せんもん】にしているわけですが、わたしのような文献【ぶんけん】を扱【あつか】う者【もの】の立場【たちば】からすれば、もっと史料【しりょう】を大切【たいせつ】にすべきではないかと思【おも】うんです。

I specialize in history, and from the standpoint of someone like me who handles literature, I think we should value historical sources more.

Here, わけ marks a prologue ("I specialize in history") and provides the foundation for the following statement: it informs the listener of how qualified the speaker is to make such a statement. わけ could be replaced by の (ん) in this example.

## Forming Sentences with わけだ

The rules for わけ follow the normal rules for forming a subordinate clause before a noun: the clause must end in a plain form, with the exception that (plain present) な-adjectives connect to わけ with な, and (plain present) nouns can connect with either な or (less commonly) の:

Often the speaker will use という to "wrap up" the preceding clause (or sentences) and use it to modify わけ (というわけだ). This doesn't change the usage, and the rules for using という are the same as those for the use of と to mark a quote or thought. This use of という is often used at the beginning of a sentence as a transition:

というわけで、…

So with that, …

This is especially common in TV or radio shows when the host needs to press the show forward or move on to the next topic. The という wraps up the preceding statements into わけ and essentially means, "Now that all this has been said, let's move on." というわけで has the following colloquial forms:

ちゅうわけで (a slur of というわけで)

てなわけで (using て for という, but as to where the な comes from, your guess is as good as mine)

ということで is also used as a transition with a meaning similar to というわけで.

## Negative Forms of わけ

There are at least four negative forms of わけ, each with slightly different meanings. One is using わけだ after a negative clause, which shows up in the examples here. This answer is getting too long to cover these, so I will simply list the other three here and wait for those interested in more complete explanations to ask a question:

• ～わけがない: There's no way that ～
• ～わけではない: It's not as though ～
• ～わけにはいかない: It's not possible to ～

Regarding the usage, your answer is far more accurate than mine. My answer just concentrated on the structure of the sentence, which is what was asked. The usage part that I added was not intended to be extensive. – None – 2011-07-28T00:35:48.847

[[ てなわけで (using て for という, but as to where the な comes from, your guess is as good as mine) ]] Maybe ～というようなわけで??? – istrasci – 2011-07-28T01:35:20.170

Perhaps this warrants its own question, however, is it possible to replace some of these with ということ? For example: "波がずいぶん荒いですね。今日は船が出せないわけですか。" into "波がずいぶん荒いですね。今日は船が出せないということですか。"　How does the feeling of the sentence change if this is possible? – phirru – 2011-07-28T02:40:09.373

@istraci: That sounds plausible. – Derek Schaab – 2011-07-28T02:50:10.683

1@phirru: Part of the analysis in the paper I linked makes note of when you can replace each of the five uses of わけだ with either はずだ or ことになる (which can be very close to ということだ). There's a table in the conclusion that summarizes when these substitutions are allowed, but unfortunately there are many exceptional cases within each usage of わけだ (such as whether the clause marked by わけだ is unknown, known, or an unconfirmed past event), so the only way to fully explain the difference would be to translate the entire paper. – Derek Schaab – 2011-07-28T02:50:16.267

@Derek Schaab: Thank you! I haven't had a chance yet to read the paper yet, I'll give it a look as soon as possible. – phirru – 2011-07-28T02:52:39.660

3@sawa: Duly noted. But since language hacker's question included the statement that there is "a certain way of talking where you can end just about anything you say in わけ", I deduced that the OP, in addition to wanting to know how to construct such sentences, is in fact unclear on why and how one would use わけ. (I also know from past teaching experience that this is a particularly tricky bit of Japanese for non-natives to learn, so I imagine many others on this site will benefit from a thorough explanation.) – Derek Schaab – 2011-07-28T02:55:17.947

1Derek, this is a great summary of the paper and will no doubt be helpful to people looking for info on わけ in general, but my interpretation of the question was that language hacker was asking about the common colloquial use of "category 5" in particular, where わけ appears like a sentence-final particle [specifically NOT followed by だ] affecting implication/discourse structure more than meaning. Maybe it would be nice to throw a note at the top covering that specific colloquial usage before diving in to the full story? – Matt – 2011-07-28T03:07:15.753

To be fair, it's quite hard to determine what exactly the question was asking. There are many ways to "end a sentence in wake" which have been discussed here. – phirru – 2011-07-28T03:15:10.560

1@Matt: Without an example sentence from the OP we can only guess at which usage is being questioned. :) As far as わけ not followed by だ, this is common in informal speech and not limited to わけ. Borrowing from an example of the first case, we could easily say: 「日本時間のちょうど正午につくわけ。」. The fact that だ is missing doesn't change the function of わけ. Similarly, 「今日は定休日。」 still means the same as 「今日は定休日だ。」, even though the だ is dropped. – Derek Schaab – 2011-07-28T03:21:19.203

Yes, I know that だ-dropping is common in informal speech, but I am talking about a separate phenomenon, one where わけ is used almost as a sentence-final particle and actually can't be combined with だ without changing in nuance. But I accept that the line between this and a だ-dropped わけだ is very iffy and calls for better evidence than my "it seems to me", so, peace. (Re interpretation of the question, quite true! My assumption is based on the "just about anything you say" part of the question specifically; this struck me as a reference to the semantically bleached わけ I mention above.) – Matt – 2011-07-28T04:20:22.570

For "こうして二人は結婚して、幸せに暮らしたわけです。" would "And of course the two married and lived happily." be a better translation? It has that same 'conclusion from reasoning' that the rest of it does. The conclusion comes from facts outside the conversion, like the fact that all fairy tales have a happy ending. – William – 2011-07-28T10:56:12.050

2@William: Using わけ to give a conclusion (Y→Z) requires some level of objectivity. In other words, given the evidence, anyone could form the conclusion marked by わけ. This objectivity is not present in the example sentence you're referring to, since the preceding context (whatever it is) does not always lead to the logical conclusion that the two married and lived happily. It is a mere statement of fact known only to the speaker. This is why わけ can be left out without affecting the meaning, which is what Yokota was getting at in her paper. – Derek Schaab – 2011-07-28T12:25:29.513

3@Derek Schaab: In my grammar book this is explained as follows: "In casual conversation wake, an informal form of wake da, is used quite frequently to give slight emphasis to a fact when the speaker does not expect the hearer to know about it.". Which I think sums it up quite nicely. – phirru – 2011-07-28T13:37:18.353

@phirru: That matches usage #4 on another page I found which sums up わけだ: 私が声をかけても彼は知らん顔をしているわけです。 ("I even try talking to him, and he's just standing there looking like he doesn't see me.") It's kind of a pain to translate into English well, and definitely counts as another one of those case-by-case constructions.

– Derek Schaab – 2011-07-28T13:45:54.317

As mentioned above I was asking about the use of わけ at the end of a sentence and not わけだ. I heard it used at the end of a series of questions. What does it mean when it's at the end of a question? – language hacker – 2011-07-28T14:15:29.130

1@language hacker: わけ and わけだ are merely alternate versions of the same thing, as has been clarified in the comments here. You'll have to provide an example sentence so I can tell you which usage pattern it fits into. There's no "わけ(だ) always means X" rule. – Derek Schaab – 2011-07-28T14:36:55.973

わけ is a noun meaning 'reason', but it might be better translated as 'circumstances' as Matt comments. When you put it at the end of a sentence, you are turning that sentence into an appositive clause modifying that noun. When the predicate is an adjectival noun (also called na-adjective), you need to change the ending into the adnominal ending (-な). The word-to-word translation will be (there is) reason that ..., or the circunstances were that ....

In actual usage, it does not mean much, but is used when you want to establish intermediate steps for explaining something.

'He was there.'

'{Reasonablly/The circumstances were that/Now/Actually}, he was there.'

'He is quiet.'

'{Reasonablly/The circumstances were that/Now/Actually}, he is quiet.'

3Might it be better to view the わけ in this case as having a meaning closer to English "circumstances" than "reason"? e.g. 彼がそこのいたわけ = "(The circumstances were that) he was there" The meaning (he was there) is the same, but the implication as a speech act is different. (Here I tend to agree with your explanation that it used as an intermediate step in an explanation; you are not just observing that he was there, but setting the scene in which his being there has bearing on what is to happen next.) – Matt – 2011-07-27T23:10:31.230

@Matt I think your translation is better. Thanks. – None – 2011-07-27T23:35:25.937
