Speaking well in quote Len revised (8)
I believe the answer is:
eloquent
'speaking well' is the definition.
'eloquent' can be an answer for 'speaking' (thesaurus). I am unsure of the 'well' bit.
'quote len revised' is the wordplay.
'revised' is an anagram indicator.
'quote'+'len'='quotelen'
'quotelen' anagrammed gives 'ELOQUENT'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for eloquent that I've seen before include "Possessing fine flow of words" , "Vividly expressive" , "Well-spoken - articulate" , "Persuasive, as a speaker" , "Good at speaking" .)
