Marvel when its unusually clear on the motorway (7)
I believe the answer is:
miracle
'marvel' is the definition.
(I've seen this in another clue)
'unusually clear on the motorway' is the wordplay.
'unusually' indicates an anagram.
'on' indicates putting letters inside (as in clothing 'on' a person).
'the motorway' becomes 'mi' (resembles M1, English motorway).
'clear' with letters rearranged gives 'racle'.
'racle' enclosing 'mi' is 'MIRACLE'.
'when its' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for miracle that I've seen before include "Supernatural occurrence" , "Extraordinary event" , "It's said to happen by the divine intervention" , "Saintly deed" , "Remarkable and welcome event" .)
