In exquisite style if truth be told, English article written earlier (10)
I believe the answer is:
ethereally
'in exquisite style if truth be told' is the definition.
I can't tell whether this definition defines the answer.
'english article written earlier' is the wordplay.
'english' becomes 'e' (abbreviation).
'article' becomes 'the' (the definite article in English).
'written earlier' becomes 'really' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'e'+'the'+'really'='ETHEREALLY'
Can you help me to learn more?
(Other definitions for ethereally that I've seen before include "in heavenly style" , "Spiritually" , "airily" .)
