Blocking complaint he waylaid to some extent (2,3,3)
I believe the answer is:
in the way
'blocking' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'complaint he waylaid to some extent' is the wordplay.
'to some extent' says the answer is hidden in the clue.
'IN THE WAY' can be found hidden inside 'complaint he waylaid'.
Can you help me to learn more?
(Other definitions for in the way that I've seen before include "causing a blockage" , "Impeding one's progress" , "Being . . . . . . . . like 11 Across" , "Causing obstruction" , "Obstructing" .)
