For instance, if I wanted to ask if a food was tasty, I want to know all
linguistic options that I have and, preferably, the nuances between them.
These are all the short, potentially appropriate answers that I can think of
at the moment, but I do not really understand them:

  * 食べ物が美味しさですか?
  * 食べ物が美味しいんですか?
  * 美味しい食べ物ですか?
  * 食べ物の美味しさがありますか?

question
adjectives questions i-adjectives
Using i-adjectives at the end of (Or really anywhere in...) a sentence?
Let's look at your sentences and explore their meaning.

> 食べ物が美味しさですか

This says, "Is the food tastiness?" I don't think that's what you want to say.

> 食べ物が美味しいんですか

This could possibly work, but it still sounds a bit off to me. (But, I'm not a
native speaker.) What strikes me odd here is the use of the particle が. Had
you written it as

> 食べ物は美味しいんですか

to my non-native ear, that sounds better.

> 美味しい食べ物ですか

This just says, "Is it tasty food?" This sounds perfectly fine; perhaps this
works for you. But, is it really saying what you want? For example,

> 日本料理はおいしい食べ物ですか

"Is Japanese cuisine tasty food?" That could make sense.

> 食べ物の美味しさがありますか

This sounds kind of weird, "Do you have the tastiness of food?"

This one you could probably change a bit, to

> 食べ物は美味しさがありますか

"Does this food have any taste to it?" Perhaps you think the food is too
bland.

Probably what you want to ask is just

> 食べ物はおいしいですか

"Is the food tasty?"

answer
Let's look at each of your sample sentences in turn.

## 食べ物が美味しさですか?

Breaking this down word for word:

  * [食]{た}べ[物]{もの}  
eating-thing → food

  * が  
[subject particle]

  * [美味しさ]{おいしさ}  
deliciousness (as a degree or amount)

  * です  
[copula]: is, are

  * か?  
[question marker]

Putting this together:

> 食べ物が美味しさですか?  
>  Is food [a degree of] deliciousness?

That doesn't make a lot of sense, but I suppose it might be a valid question,
perhaps in a philosophical or epistemological context. :)

## 食べ物が美味しいんですか?

  * [食]{た}べ[物]{もの}  
food

  * が  
[subject particle]

  * [美味しい]{おいしい}  
delicious

  * ん  
contraction of の. In questions, adds a nuance shift a bit like the change from
"is it X?" to "is it that X is the case?"

  * です  
[copula]: is, are

  * か?  
[question marker]

Putting this together:

> 食べ物が美味しいんですか?  
>  Is it that food is delicious?

Depending on the context, this could be a reasonable question.

## 美味しい食べ物ですか?

  * [美味しい]{おいしい}  
delicious

  * [食]{た}べ[物]{もの}  
food

  * です  
[copula]: is, are

  * か?  
[question marker]

Putting this together:

> 美味しい食べ物ですか?  
>  Is [it / this] delicious food?

Depending on the context, this could also be a reasonable question.

## 食べ物の美味しさがありますか?

  * [食]{た}べ[物]{もの}  
food

  * の  
[possessive particle]

  * [美味しさ]{おいしさ}  
deliciousness (as a degree or amount)

  * が  
[subject particle]

  * あります  
there is / there are (or in questions, is there / are there)

  * か?  
[question marker]

Putting this together:

> 食べ物の美味しさがありますか?  
>  Is there the food's deliciousness?

This doesn't make much sense either.

* * *

I hope the word-for-word breakdowns help you understand these word forms and
structures better.
