Bishop in brief broadcast to expose liar (6)
I believe the answer is:
fibber
'expose liar' is the definition.
'fibber' can be an answer for 'liar' (fibber is a kind of liar). I'm unsure of the 'expose' bit.
'bishop in brief broadcast' is the wordplay.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'in' is an insertion indicator.
'broadcast' indicates an anagram (letters scattered or cast around).
'brief' is an anagram of 'fiber'.
'b' inserted into 'fiber' is 'FIBBER'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for fibber that I've seen before include "One who tells porkies" , "Teller of white lies" , "Teller of little lies" , "Storyteller" , "Person telling small lies, perhaps a child" .)
