Is it the swan ship Galadriel uses in Farewell to Lorien?

It is indeed! Well done, Mith! Over to you.

Nice choice! Hmm something simple this time for me I think. Okies off you go...

Person?

Thing?

So it's not an immaterial concept which also happens to be both a place and a life-form?:p

No, don't count that one. Something different - Is it green?

Person? No
Thing? Ummmmmm I suppose you could call it that ...most things are things
Immaterial concept also place and life form? No but on elements you might get one or two out of three!

Green ., yes!

Is it a plant?

(By "thing" I meant object. Should have been more specific, but... whatever.)

It isn't a plant and it isn't an object

Place?

Yes a place.

Forest?

Grassland?

Grassland/Forest ? Is neither has both to a point.

Is it in Aman?

The corollaire?

No and so no....

Is it a country (eg Gondor)?

Not a country

A region?

Region no...

In ME?

Very much so ....

Is it Middle-Earth?

Hey, that was my answer! Don't tell me that Mith used it!

Erm, um, a city/town?

I wouldn't go back to that! It isn't a tricksy one honest.

Hmm... so it's a place more closely circumscribed than a country or region, right?
Did Elves ever dwell there?

Not that is recorded to my knowledge. And your assumption is correct.

So is it a city/town?

Strictly speaking it is the location of a city/town but that is a fine distinction so effectively yes.

Is it Tharbad?

Nope

Hm, I think we'll have to tackle this the old-fashioned way.
North of the White Mountains?

Oh Pitch and your green was so inspired,... there have been answers with all salient elements just not right option.... yes noth of White Mountains.

South of Dol Guldur?

West of Misty Mtns?

Not South of Dol Guldur
Yes West of the Misty Mountains,

Do hobbits live there?

No not the Shire - if you misses my answer to Pitch it is smaller than a country and no Elves. She Shire is a country IMO and I would have hesitated to say now Elves because of WoodyEnd - a permanent temporary Elf residence!

*sighs* "Green" was the most random question ever, but the best one yet!...

Was it populated/inhabited by people at the time of the War of the Ring?
