Released foreign article before spring (7)
I believe the answer is:
unbound
'released' is the definition.
(thesaurus)
'foreign article before spring' is the wordplay.
'foreign article' becomes 'un'.
'before' means one lot of letters go next to another.
'spring' becomes 'bound' (bounding is a kind of springing**).
'un'+'bound'='UNBOUND'
(Other definitions for unbound that I've seen before include "Not restricted" , "Like Shelley's Prometheus" , "Loose" , "Prometheus ... (Shelley)" .)
