What is the general way to say something like "in your room?" without a verb?


For example, 部屋にいました would be "was in your room", but is it possible to say
just "in your room" without the verb? Something like 部屋に? Or 部屋で?




I assume you already understand the [basic difference between に and
で](https://japanese.stackexchange.com/q/60/5010) when there is a concrete
verb.

So, in what context do you want to say "In one's room"? Is this an answer to a
certain question, or is this a title or something?

**If this is an answer to a certain question** , there must be a conrete
implied verb, and your particle must correspond to that verb.

> 「どこ **で** 財布を見つけたの？」「部屋 **で** 。」  
>  "Where did you find my wallet?" "In the room."
>
> 「彼はどこ **に** いるの？」「部屋 **に** 。」  
>  "Where is he?" "In the room."

Note that you can also just say 「部屋。」 without any particle in both examples.

**If there is no specific implied verb** (e.g., if "In Your Room" is the title
of a song), 部屋で and 部屋に both work fine. Still, there is a small difference in
meaning. 部屋で sounds like something is going to happen in the room, because で
is the particle to describe the location of an action. On the other hand, 部屋に
focuses on the existence, and sounds like someone or something is there.

For example, there is a manga/movie titled この世界の片隅に, which is translated as
[_In This Corner of the
World_](https://en.wikipedia.org/wiki/In_This_Corner_of_the_World). Since に is
used, this title sounds like "I am here in this corner of the world!" or "This
small life exists in this corner of the world" rather than "I'll do something
here!"
