About わけだ

One of the most misunderstood words in Japanese is (わけ). Of the many ways it can be translated, the most common are 'reason', 'cause', 'meaning', or 'conclusion'. Despite this, it may be beneficial to consider it almost identical to an equally versatile English word 'so'.
In all of its uses, わけ simply highlights the plain existence/determination of something in the same way that 'so' does in English. This can be seen in its most basic form in わけだ. A combination of わけ and the auxiliary verb .
わけだ will be used at the end of sentences, and is sometimes preceded by という. This use is often translated as 'for the reason of (A)', 'no wonder its (A)', or 'its (A), as you'd expect'. Realistically though, it just means 'it is so that it's (A)', or 'so it's (A)'.
  • 事故(じこ)電車(でんしゃ)(おく)れた?だから(めずら)しく(おく)れて()というわけだ
    The train was late due to an accident? So that's why you came in unusually late.
  • (ゆび)(ほね)()ていたですね。から(ゆび)(うご)かしたら(いた)かったという(わけ)ですね。

  • やっぱり全然(ぜんぜん)練習(れんしゅう)してないでしょ?どうりで一年(いちねん)たっても下手(へた)わけだ
    As I expected, you didn't practice at all, did you? No wonder you haven't improved even after a year.
  • 今日(きょう)休日(きゅうじつ)か。だから定休日(ていきゅうび)わけだ
    Today is a holiday, isn't it? So that's why they are closed today.
Due to わけ being a noun, it will need to follow the attributive form of whatever word comes before it. As we can see 'so' and わけ have an extremely close pattern of nuances, ranging from 'because', all the way through to simple emphasis (like with 'naturally', and 'as you'd expect').
わけ may also be used in questions, implying that the speaker is trying to determine something that they have heard. わけだね 'so its (A) right?', and わけですか 'so is it that (A)?' are good examples of this.
  • (おれ)一緒(いっしょ)くないわけだね?()かったよ。
    So you are saying that you don't want to be with me, right? I understand.
