Awfully hot, so to me attractive (9)
I believe the answer is:
toothsome
'attractive' is the definition.
(thesaurus)
'awfully hot so to me' is the wordplay.
'awfully' indicates anagramming the letters.
'hot'+'so'+'to'='hotsoto'
'hotsoto' with letters rearranged gives 'toothso'.
'toothso'+'me'='TOOTHSOME'
(Other definitions for toothsome that I've seen before include "Pleasing" , "Temptingly tasty" , "attractive" , "Inviting" , "It's just like a T-Rex" .)
