Can former nurse let go? (6)
I believe the answer is:
loosen
'let go?' is the definition.
(thesaurus)
'can former nurse' is the wordplay.
'can' becomes 'loo' (loo is a kind of can).
'former nurse' becomes 'sen' (I've seen this in other clues).
'loo'+'sen'='LOOSEN'
(Other definitions for loosen that I've seen before include "Work free" , "Undo, make less tight" , "Undo a little" , "relax or tear apart" , "Untie, relax" .)
