It's pitched outside (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
tent
'it's pitched outside' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tent that I've seen before include "Marquee" , "Bivvy" , "some guys held on to?" , "Camping accommodation" , "Portable shelter - red wine" .)
