First bloke to carry bird across the Nile? (5,3)
I believe the answer is:
aswan dam
'across the nile?' is the definition.
(dam across the River Nile)
'first bloke to carry bird' is the wordplay.
'first bloke' becomes 'Adam' (first man in the Bible).
'to carry' indicates putting letters inside.
'bird' becomes 'swan' (swan is a kind of bird).
'adam' enclosing 'swan' is 'ASWAN DAM'.
(Other definitions for aswan dam that I've seen before include "Huge structure in Africa" , "Egypt's lake district" , "Egyptian water barrier" , "massive barrier" , "Nile construction of 1902" .)
