She's in the street, helping (5)
I believe the answer is:
ethel
'she's' is the definition.
(I've seen this before)
'in the street helping' is the wordplay.
'in' indicates a hidden word.
'ETHEL' can be found hidden inside 'street helping'.
(Other definitions for ethel that I've seen before include "Female name" , "Trying not to be seen" , "Perhaps a Barrymore" , "- Barrymore, actress" , "- Merman, US actress" .)
