Enough to correspond after a date (8)
I believe the answer is:
adequate
'enough' is the definition.
(I know that enough can be written as adequate)
'correspond after a date' is the wordplay.
'correspond' becomes 'equate' (synonyms).
'after' says to put letters next to each other.
'a date' becomes 'AD' (AD is an example).
'equate' after 'ad' is 'ADEQUATE'.
'to' acts as a link.
(Other definitions for adequate that I've seen before include "Fair to middling" , "Good or plentiful enough" , "Sufficient or all right" , "Just about sufficient, acceptable" , "Passable; enough" .)
