Attending twice today (2,7)
I believe the answer is:
at present
'today' is the definition.
(synonyms)
'attending twice' is the wordplay.
'attending twice' means two replacements for 'attending'.
'attending' becomes 'at' (I've seen this in other clues).
'attending' becomes 'present' (similar in meaning).
'at'+'present'='AT PRESENT'
(Other definitions for at present that I've seen before include "temporarily" , "these days" , "Currently, right now" , "Nowadays" , "As of now, during this time" .)
