Writer given $1000 by posh, trendy publishers (7)
I believe the answer is:
penguin
'writer given $1000 by posh trendy publishers' is the definition.
I can't judge whether this definition defines the answer.
'writer given $1000 by posh trendy' is the wordplay.
'writer' becomes 'pen' (something which writes).
'given' says to put letters next to each other.
'$u000' becomes 'g' (I've seen this in other clues).
'by posh' becomes 'u' (abbreviation for upper-class - opposite to non-U. I am not sure about the 'by' bit.).
'trendy' becomes 'in' ('in' can mean fashionable).
'pen'+'g'+'u'+'in'='PENGUIN'
Can you help me to learn more?
(Other definitions for penguin that I've seen before include "Waddling bird" , "Black and white flightless Antarctic bird" , "Black-and-white Arctic bird" , "Flightless seabird" , "Chocolate biscuit" .)
