Course initially falls short in banqueting (7)
I believe the answer is:
easting
'course' is the definition.
(I've seen this before)
'initially falls short in banqueting' is the wordplay.
I cannot really understand how this works, but
'in' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for easting that I've seen before include "distance for navigator" , "oriental course?" , "distance in another direction" , "distance measured" , "Map reference" .)
