Blackish seaside structure? (5)
I believe the answer is:
jetty
This clue could be a double definition.
'blackish seaside' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'structure?' is the second definition.
(I know that jetty is a type of architectural structure)
Can you help me to learn more?
(Other definitions for jetty that I've seen before include "Dock" , "Small landing stage" , "Wharf" , "Quay" , "Pier - landing stage" .)
