Swear in the MCG on Boxing Day? (6)
I believe the answer is:
attest
'swear' is the definition.
(attesting is a kind of swearing)
'the mcg on boxing day?' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
'on' could be 'at' (I've seen this in other clues) and 'at' is found within the answer.
The remaining letters 'est' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for attest that I've seen before include "Bear witness, declare to be true" , "Vouch for" , "Give evidence in a court of law" , "Demonstrate" , "Declare (that something is the case)" .)
