I'm a little stuck... Click here to teach me more about this clue!

'temporary home' is the definition.
(I've seen this in other clues)

I don't understand how the rest of the clue works.

(Other definitions for tent that I've seen before include "abode meant to be temporary" , "Camping accommodation" , "Marquee" , "Temporary shelter" , "Bivvy" .)

I've seen this clue in The Irish Independent.
