Spare tent used now (2,7)
I believe the answer is:
at present
'now' is the definition.
(synonyms)
'spare tent used' is the wordplay.
'used' indicates anagramming the letters.
'spare'+'tent'='sparetent'
'sparetent' with letters rearranged gives 'AT PRESENT'.
(Other definitions for at present that I've seen before include "temporarily" , "Currently, right now" , "Nowadays" , "these days" , "As of now, during this time" .)
