Dry area at the riverside in Poland (4)
I believe the answer is:
land
'dry area' is the definition.
'land' can be an answer for 'area' (land area is a kind of area). I'm not certain of the 'dry' bit.
'the riverside in poland' is the wordplay.
'LAND' is hidden in amongst the letters.
But, I am unsure how the hidden word is indicated.
'at' is the link.
Can you help me to learn more?
(Other definitions for land that I've seen before include "people" , "Take catch" , "Light" , "soil" , "Acquire" .)
