'obscure' is the definition.
(synonyms)

'speak about don awfully' is the wordplay.
'speak' becomes 'recite' (I am not sure about this - if you are sure you should believe this answer much more).
'about' indicates putting letters inside.
'awfully' indicates anagramming the letters.
'don' anagrammed gives 'ond'.
'recite' placed around 'ond' is 'RECONDITE'.
