Some of the homeless entered German location (5)
I believe the answer is:
essen
'german location' is the definition.
'Essen' can be an answer for 'location' (Essen is an example). I also know that 'german' relates to this answer.
'some of the homeless entered' is the wordplay.
'some of' indicates a hidden word.
'ESSEN' is hidden in the letters of 'homeless entered'.
(Other definitions for essen that I've seen before include "Krupp HQ (Ger.)" , "German industrial city on the Ruhr" , "European city" , "German place name" , "German industrial centre" .)
