Which noun is described by 大きな and 滑か in 「真珠貝は大きな滑かな縁の鋭い貝であった」


Is it 縁 or 貝? I have consulted two translations, and they both make different
choices.

> The shell was big and smooth and sharp-edged. (Breaking into Japanese
> Literature; trans. Giles Murray)

> The shell was sharp, with a long, gently curved edge. (trans. Matt Treyvaud)

Is this sentence ambiguous for native speakers, or would they always attribute
adjectives and modifiers to the closest noun (i.e. would the first translation
above correspond more to 縁の鋭い大きな滑かな貝であった)?




In terms of syntax, 大きな can be interpreted as modifying either 縁 or 貝. The
same is true for 滑らか, but this is almost theoretical and most people would see
'滑らかな縁' as a chunk.

In terms of meaning, it is not ambiguous mainly because people at least
vaguely know what 真珠貝 looks like. Also, whether 大きな modifies 縁 or 貝 does not
make much difference: a long edge means a large shell and vice versa.

That said, to me, 大きな modifies 貝. So literally it means _The pearl oyster was
a large shell with a smoothly-curved sharp edge._

This kind of ambiguity is common. A famous example is 黒い目のきれいな女の子, which is
said to admit 18 ways of parsing. (See
[this](https://yosikazuf.hatenadiary.org/entry/20120513/p1) for example).




I would interpret it as...

> 「真珠貝は［大きな］［滑らかな］［縁の鋭い］ **貝** であった。」  
>  The shell was big and smooth and sharp-edged.

... where 大きな, 滑らかな and 縁の鋭い modify 貝, 縁の鋭い being one chunk.

So I would read (朗読/音読) it like this:

> 「真珠貝は 大きな 滑らかな 縁の鋭い貝であった。」

... with a pause between 滑らかな and 縁.

To say "The shell had a big, smooth and sharp edge", with 大きな and 滑らかな
modifying 縁, I would say more like...

> 「真珠貝は 大きく滑らかで鋭い縁の貝であった。」 大きく, 滑らかで and 鋭い all modify 縁. (This can still be
> ambiguous, though.)  
>  or maybe...  
>  「真珠貝は 縁が 大きく滑らかで鋭い貝であった。」(This one can also be ambiguous, though: "a large-
> edged, smooth, and sharp shell" (縁が大きく、滑らかで鋭い貝)? "had a large and smooth
> edge, and was sharp" (縁が大きく滑らかで、鋭い貝)?)
