Unintentionally say tenancy taken by cricket fielder (3,4)
I believe the answer is:
let slip
'unintentionally say' is the definition.
(as in letting slip a secret)
'tenancy taken by cricket fielder' is the wordplay.
'tenancy' becomes 'let' (I am not sure about this - if you are sure you should believe this answer much more).
'taken by' says to put letters next to each other.
'cricket fielder' becomes 'slip' (cricket position).
'let'+'slip'='LET SLIP'
Can you help me to learn more?
(Other definitions for let slip that I've seen before include "Reveal accidentally, or allow to skid?" , "Allow to fall or reveal a secret accidentally" , "Allow to escape (information etc)" , "Fail to keep Secret" , "accidentally revealed" .)
