Come east in attempt to expose betrayal? (9)
I believe the answer is:
treachery
'expose betrayal?' is the definition.
'treachery' can be an answer for 'betrayal?' (synonyms). I am not sure about the 'expose' bit.
'come east in attempt' is the wordplay.
'come' becomes 'reach' (reaching is a kind of coming).
'east' becomes 'e' (abbreviation).
'in' is an insertion indicator.
'attempt' becomes 'try' (synonyms).
'reach'+'e'='reache'
'reache' inserted inside 'try' is 'TREACHERY'.
'to' is the link.
Can you help me to learn more?
(Other definitions for treachery that I've seen before include "lack of loyalty" , "Betrayal of trust" , "Treason" , "perfidious conduct" , "disloyalty" .)
