Failure surprisingly exposing requirements of angler (5)
I believe the answer is:
lures
'requirements of angler' is the definition.
The definition and answer can be both related to thinking as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'failure surprisingly exposing' is the wordplay.
'exposing' says the answer is hidden in the clue (I've seen 'exposes' mean this).
'LURES' is hidden in the letters of 'failure surprisingly'.
Can you help me to learn more?
(Other definitions for lures that I've seen before include "Rules with decoys" , "Draws" , "Baits or attractions" , "Baits, decoys" , "Tempts or entices" .)
