Central section of Lexington Avenue (4)
I believe the answer is:
nave
'central section' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'of lexington avenue' is the wordplay.
'of' indicates a hidden word.
'NAVE' can be found hidden inside 'lexington avenue'.
Can you help me to learn more?
(Other definitions for nave that I've seen before include "Take no risks" , "Central area in a church" , "Central space in church" , "Central part of church" , "Central place in church" .)
