Bishop will speak loud untruths, suggesting nerves (11)
I believe the answer is:
butterflies
'nerves' is the definition.
Although both the answer and definition are plural nouns, I don't see how they can define each other.
'bishop will speak loud untruths' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'will' is a charade indicator (letters next to each other) (I've seen this in other clues).
'speak' becomes 'utter' (synonyms).
'loud' becomes 'f' (short for forte - 'loud' in music).
'untruths' becomes 'lies' (lie is a kind of untruth).
'b'+'utter'+'f'+'lies'='BUTTERFLIES'
'suggesting' is the link.
Can you help me to learn more?
(Other definitions for butterflies that I've seen before include "coppers?" , "insects?" , "Skippers, for example" , "Painted ladies, for example" , "Nervous tremors in the stomach" .)
