Parts of Poplar East? (5)
I believe the answer is:
areas
'parts' is the definition.
(area is a kind of part)
'of poplar east?' is the wordplay.
'of' indicates a hidden word.
'AREAS' can be found hidden inside 'poplar east'.
(Other definitions for areas that I've seen before include "Zones" , "Localities" , "Geographical regions" , "Spaces covered by two-dimensional surfaces" , "Places" .)
