Runs free in confusion before quiet jog (7)
I believe the answer is:
refresh
'jog' is the definition.
(thesaurus)
'runs free in confusion before quiet' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'in confusion' indicates anagramming the letters.
'before' means one lot of letters go next to another.
'quiet' becomes 'sh'.
'free' anagrammed gives 'efre'.
'r'+'efre'+'sh'='REFRESH'
(Other definitions for refresh that I've seen before include "give life again to..." , "Give new energy to" , "brace" , "Enliven once more" , "Give new vigour to" .)
