Is it so fantastic to have to carry this plough? (5,4)
I believe the answer is:
great bear
'is it so fantastic to have to carry this plough?' is the definition.
'great bear' can be an answer for 'plough?' (I've seen this before). I am unsure of the rest of the definition.
'carry this plough?' is the wordplay.
I cannot really see how this works, but
'carry' could be 'bear' (bear can mean to transport or carry) and 'bear' is found within the answer.
'plough?' could be 'great' (I have seen 'The Plough ' mean 'great' so perhaps 'plough' could also mean 'great') and 'great' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for great bear that I've seen before include "'Large ursine in the heavens (5,4)'" , "Plough constellation" , "Major stars" , "Ursa Major" , "Large animal - same as 7" .)
