In this establishment? In another establishment (4)
I believe the answer is:
here
'in this establishment?' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'in another establishment' is the wordplay.
'in' indicates a hidden word.
'HERE' is hidden within 'another establishment'.
Can you help me to learn more?
(Other definitions for here that I've seen before include "In this place - present" , "Present - at this point" , "In attendance" , "At this stage" , "The present location" .)
