Tiny miracle – no surprise there (5,6)
I believe the answer is:
small wonder
'no surprise there' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'tiny miracle' is the wordplay.
'tiny' becomes 'small' (similar in meaning).
'miracle' becomes 'wonder' (I've seen this in another clue).
'small'+'wonder'='SMALL WONDER'
Can you help me to learn more?
(Other definitions for small wonder that I've seen before include "Dwell on Mars (anag) - it's not surprising" , "It isn't surprising!" .)
