The foreign-edited quote about Nationalist leader is persuasive, whatever you say (8)
I believe the answer is:
eloquent
'persuasive whatever you say' is the definition.
I can't tell whether this defines the answer.
'the foreign-edited quote about nationalist leader' is the wordplay.
'the foreign' becomes 'el' (**).
'edited' indicates an anagram.
'about' indicates putting letters inside.
'leader' suggests taking the first letters.
The initial letter of 'nationalist' is 'n'.
'quote' with letters rearranged gives 'oquet'.
'oquet' going around 'n' is 'oquent'.
'el'+'oquent'='ELOQUENT'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for eloquent that I've seen before include "Axilla; oxter" , "Effective in speech" , "Forceful and persuasive in speech" , "Clearly expressive" , "Using language fluently and effectively" .)
