Force Sal out into the open-air (8)
I believe the answer is:
alfresco
'the open-air' is the definition.
(thesaurus)
'force sal out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'force'+'sal'='forcesal'
'forcesal' anagrammed gives 'ALFRESCO'.
'into' acts as a link.
(Other definitions for alfresco that I've seen before include "exposed to the fresh air" , "Out of doors" , "Outside" , "out of the house" , "Outdoors, meal perhaps" .)
