I’m not quite sure what I’m doing wrong here?

Hey :bowing_man:

It should be 忘れちゃった instead of 忘れてちゃった。
The て form is used, but て itself is removed and ちゃう is attached to what is left from it.

It goes like this:

わすれるーmake て form→忘れてーremove て→忘れーadd ちゃう→忘れちゃうーpast form→忘れちゃった

The structure section was a bit unclear, so I have fixed it:

I hope it helps!
Cheers :+1:

Ah that explains what went wrong, thank you so much! All the examples used てしまう as well, so it got quite confusing :sweat_smile: Maybe have some examples alter readings in this case, or maybe alter readings at random even :open_mouth:

(Please let other people’s subsequent hearts dictate whether I’m alone on this, but…)

I really don’t like the mixing of this grammar point with the volitional, in the example problem
今日は冬休みの宿題を全部 してしまおう.

I’d much rather practice this new grammatical form on its own, and then mix with other grammatical elements like volitional, later on, when I feel more comfortable.

Or - at very least - I’d like to humbly request a “soft error” here, reminding me that (inexplicably) this question is asking for a variation what’s been taught in the ‘Grammar Info’ section.

Thank you for all you do.

Again… could be just me. Some brains probably appreciate the mixing of lower-level grammar points.

What is the English translation of the sentence? I would say that if the translation says something along the lines of ‘let’s’ then it would be OK because the aim of BunPro is to build on already learned grammar by mixing it into sentences in new grammar.

I think this is a good idea yeah.

@chrischriskurisu Thank you for your feedback. As @matt_in_mito mentioned, the goal of Bunpro is to use previously studied grammar in sentences so that they both build off of what you have already learned and introduce you to new contexts/situations where that particular grammar point can be used.

The casual volitional is introduced in Lesson 4, while てしまう does not appear until Lesson 8, so unless you are adding entire lessons to your reviews daily, this should give you plenty of time to familiarize yourself with the volitional and how it is used.

Before you type your answer, the hint “[casual + volitional]” is shown in the answer blank (in the Japanese sentence). If you have all of your hints turned on, you should also be seeing "[casual・volitional (can also be translated as “let’s”)].

If you type in the plain form (dictionary form) or the polite ます-form, you will get the hint “Think ‘will’ (volitional).”

We try our best to guide you along if you happen to forget a certain form, rather than marking you wrong outright. We are always trying to improve how the system works by making it more intuitive and your feedback helps us do that. Cheers!

My apologies. I wasn’t clear that I am attempted to practice the ~ちゃう form. しまう seems like a piece of cake, so I’m practising the variations.

So I typed しちゃう… which of course is wrong because it doesn’t account for volition. My bad.
I can see that this is an error, but I don’t know if it’s because:

  • One simply cannot express 〜ちゃう with する?
  • One cannot change 〜ちゃう to make it volitional.

So… this could totally be my bad. But any time I find myself in a situation where I think “I’m wrong but I don’t know why”, I can’t help but wonder if it’s me & my own failings, or if the question itself could use some tweaking.

Again… if you never see any hearts or upvotes for me comment, then you’ll know I’m an outlier and this is really a non-issue. Sorry again for the bother.

@chrischriskurisu

I see! That’s my bad for not realizing that you could have been trying different variations.

If you have to ask these types of questions then we are not doing a good enough job of explaining why you got an answer wrong (or in this case, not providing a hint at all). I have gone back through the questions to add that てしまう and 〜ちゃう variations are both acceptable in this case but sound a little more direct/final. That being said, we would still like you to practice the volitional form here to help reinforce what you have previously learned.

Cheers!

@Pushindawood Thank you for your feedback. Okay, I will continue to practice the volitional form.

Thank you for your consideration with updating the responses to 〜ちゃう based answers. I appreciate your open mindedness and dedication. I realize that there can be countless permutations of error handing, since grammar is not always a “yes or no” kind of thing. So thank you again.
