About けっこう

結構(けっこう) is a な-Adjective that is actually used more frequently as a sentence altering adverb, than it is as a な-Adjective. What this means is that it is regularly used before an entire phrase (without な or だ), and it will modify the entire sentence. The most common meaning that 結構(けっこう) has is 'quite' (a bit/a lot).

Fun Fact

結構(けっこう) is used very similarly in Japanese to 'no thank you', or 'I'm fine thanks' in English. For example, if someone asks you if you want to try a sample in a shop, most people would just say 結構(けっこう)です.

Examples

Why is the kanji for daijoubu allowed but not the hiragana?

Sorry about that. It looks like the kanji answer was accidentally added to alternative answers making it appear when you cycle through the hints. We still do not have a way to answer with kanji set up in the system, but hope to have it available soon.

I have updated the review question to allow the hiragana answer.

Thank you for reporting it!
Cheers

Just a suggestion, but I think the “quite” and “no thank you” meanings should be separated into different grammar points. Since the SRS memorising system is supposed to help you remember by making you recall things just before you forget them, having two alternative meanings in the same point means that you’re not recalling the other one when you should be, according to how the system works.

Obviously where the meanings are linked or close, you could remember them both together as one grammar point despite the sentence having only one particular wording. For example, all the 他 sentences are about ‘others’, even if the wording sometimes becomes “anything else”, etc. But I think for the two meanings here, there’s no obvious connection.

Edit: On second thoughts, since “quite” is just a word, and not a grammar point, perhaps that could just be taken out of the examples so it’s all about “no thank you”?
