Bent a nail on the deck (5)
I believe the answer is:
lanai
'deck' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'bent a nail on' is the wordplay.
'bent' indicates anagramming the letters.
'on' says to put letters next to each other.
'a'+'nail'='anail'
'anail' anagrammed gives 'LANAI'.
'the' is the link.
Can you help me to learn more?
(Other definitions for lanai that I've seen before include "Hawaiian veranda" , "Hawaiian living area" , "Place where Hawaiians live" .)
