Stop regularly to conceal reek from batter (5)
I believe the answer is:
thump
'batter' is the definition.
(thesaurus)
'stop regularly to conceal reek' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'to conceal' means one lot of letters goes inside another.
'reek' becomes 'hum' (I've seen this before).
The alternating letters of 'stop' are 'tp'.
'tp' enclosing 'hum' is 'THUMP'.
'from' is the link.
(Other definitions for thump that I've seen before include "clobber" , "Pound" , "Smack" , "Heavy blow with the hand" , "(Sound of) heavy blow" .)
