I do not understand the meaning of のを:

a. 彼は家を買った。 しかも大きい庭付きのを(だ)。 (だ is indicated as optional)

Is it different from:

b. 彼は家を買った。 しかも大きい庭付きだ。 (I'm not sure if this is grammatical)

c. 彼は家を買った。 しかも大きい庭付きのだ。

What does it mean when the copula takes on a direct object? I have so far only encountered AはBだ, AがBだ, Bだ but I have not seen を directly preceding the copula before.

  • Where did you see such sentence ?

  • @oldergod. It is taken from A Dictionary of Intermediate Japanese Grammar. It is one of the example sentences for illustrating the use of しかも.

It is a (pseudo) cleft sentence with the noun phrase and the topic ellided. I thought there was a variety among native speakers who accept and who don't.

'In fact, he bought a house that has a large garden.' (Original sentence)

'In fact, what he bought was a house that has a large garden.' ((Pseudo) cleft)

'In fact, what he bought was one that has a large garden.' (Ellipsis of a noun phrase)

'In fact, (what he bought was) one that has a large garden.' (Ellipsis of the topic)

It is different from the other sentence, in which simply is ellided:

'In fact, (it) has a large garden.'

  • The final sentence is still slightly different from the one I quoted. What happened to the を particle? In fact I noticed it disappeared at the point where the cleft occurs. Is を optional?

  • That is what I mentioned at the top. Technically, it seems that the existence vs. the absense of is considered to correspond to cleft vs. pseudo cleft sentences in English: It is one that has a large garden (that he bought) (cleft) vs. (What he bought was) one that has a large garden (pseudo cleft).

In a., -no is the genitive case marker that connects two noun phrases, and -wo is the accusative case marking the direct object of the verb. The problem that you are likely having is in understanding the ellipse coming from the first sentence. You should interpret it as follows:

"He bought a house. In fact, a big one with a garden."

    In your explanation, it is not clear where came from.

  • When the verb is elided, does it become optional to use the copula after を ?
