Obvious miracle arranged outside (5)
I believe the answer is:
clear
'obvious' is the definition.
(similar in meaning)
'miracle arranged outside' is the wordplay.
'outside' indicates a hidden word (a word is around or outside the answer).
'CLEAR' can be found hidden inside 'miracle arranged'.
(Other definitions for clear that I've seen before include "Set free of charges" , "Easy to see or understand" , "Bright" , "Exculpate" , "Transparent or cloudless" .)
