Clear out section of Tesco urgently (5)
I believe the answer is:
scour
'clear out' is the definition.
(thesaurus)
'section of tesco urgently' is the wordplay.
'section of' indicates the answer is hidden within the clue.
'SCOUR' is hidden within 'tesco urgently'.
(Other definitions for scour that I've seen before include "search in detail" , "Turn upside down" , "Full" , "Clear out" , "Clean by hard rubbing" .)
