Sporting triumph head of Lancing entered in file (7)
I believe the answer is:
blinder
'sporting triumph head' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'lancing entered in file' is the wordplay.
I cannot quite understand how this works, but
'in' is present in the answer.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for blinder that I've seen before include "Star performance" , "Marvellous performance" , "as Cornwall, as against Gloucester" , "the boy in "Equus"?" , "drunken orgy" .)
