Serpent unfortunately here (7)
I believe the answer is:
present
'here' is the definition.
(similar in meaning)
'serpent unfortunately' is the wordplay.
'unfortunately' indicates anagramming the letters (a bad or unfortunate spelling).
'serpent' with letters rearranged gives 'PRESENT'.
(Other definitions for present that I've seen before include "Serpent (anag.)" , "something not seen under a tree every day" , "host" , "Introduce < and compere < tense" , "See 12" .)
