Is there any adjective in English that would describe a quality of belonging or being in the possession of someone else who is not the speaker?

In short, what adjective would you substitute for the words in bold below:

What's inside of this bag?

I don't know. This is not my bag.


What's inside of this bag?

I don't know. This bag is not mine.


Jack, don't touch that toy car.


Because that toy is not yours.

  • To keep this consistent (and correct), the third example would be "that toy is not yours."

I'd probably use somebody else's.

  • that's not a good answer. "sb else's"? What does that mean? Is it even English? Dec 21, 2011 at 10:58

    Well, it's still not something I would recommend anyone use except in the most informal of circumstances, and certainly not in speech. Dec 21, 2011 at 11:15

    Since it's the correct answer, once you expand the silly abbreviation, I've edited it rather than add my own answer.

But notice that another's is not an adjective. I'm pretty sure that the kind of word you're describing cannot be an adjective.

  • how about simply other's?

    "other's" doesn't seem to fit in the example sentences above.

There are analogous words in other languages with the meaning sought in the OP. However, bilingual dictionaries do not show a unique equivalent word in English for them.
