Any white construction is like an obstruction (2,3,3)
I believe the answer is:
in the way
'like an obstruction' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'any white construction' is the wordplay.
'construction' is an anagram indicator (answer constructed from certain letters).
'any'+'white'='anywhite'
'anywhite' is an anagram of 'IN THE WAY'.
'is' is the link.
Can you help me to learn more?
(Other definitions for in the way that I've seen before include "Obstructing" , "Causing obstruction" , "Alpine climber's tool" , "causing a blockage" , "Impeding one's progress" .)
