Use wiles to beseech upper-class French island (7)
I believe the answer is:
beguile
'use wiles to' is the definition.
I can't judge whether this defines the answer.
'beseech upper-class french island' is the wordplay.
'beseech' becomes 'beg' (I've seen this in another clue).
'upper-class' becomes 'u' (similar in meaning).
'french island' becomes 'ile' ('island' in French).
'beg'+'u'+'ile'='BEGUILE'
Can you help me to learn more?
(Other definitions for beguile that I've seen before include "Charm, enchant" , "Charm, divert" , "Charm, entrance" , "Hoodwink" , "Charm, win the interest of" .)
