Skate, mostly like flounders, get promoted at the bar (4,4)
I believe the answer is:
take silk
'promoted at the bar' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'skate mostly like flounders' is the wordplay.
'mostly' means to remove the last letter (most but not all of the word).
'flounders' is an anagram indicator (I've seen 'floundering' mean this (letters flounder or move around)).
'like' with its final letter taken off is 'lik'.
'skate'+'lik'='skatelik'
'skatelik' anagrammed gives 'TAKE SILK'.
'get' acts as a link.
Can you help me to learn more?
(Other definitions for take silk that I've seen before include "Get legal promotion" , "Acquire shiny cloth as barrister does" .)
