It’s a wonder I’m up, right, and about to tuck into drink (7)
I believe the answer is:
miracle
'it's a wonder' is the definition.
(I've seen this before)
'i'm up right and about to tuck into drink' is the wordplay.
I cannot really understand how this works, but
'i'm' could be 'i' (I've seen this in other clues) and 'i' is present in the answer.
'right' could be 'r' (common abbreviation) and 'r' is found in the answer.
'about' could be 'c' (abbreviation for 'circa') and 'c' is found within the answer.
'drink' could be 'ale' (type of beer) and 'ale' is present in the remaining letters.
A single letter 'm' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for miracle that I've seen before include "Remarkable and welcome event" , "Inexplicable wonder" , "Unexplained wonder" , "Welcome event that's not explained by natural law" , "Saintly deed" .)
