Make a big show of direction on Doctor At Large and broadcast after all the letters (8)
I believe the answer is:
emblazon
'make' is the definition.
The definition and answer can be both to do with creating things as well as being verbs in their base form.
Perhaps you can see an association between them that I don't see?
'a big show of direction on doctor at large and broadcast after all the letters' is the wordplay.
I cannot quite see how this works, but
'a' is found in the answer.
'of' could be 'o' and 'o' is found in the answer.
'direction' could be 'n' (N is an example) and 'n' is found within the answer.
'doctor' could be 'mb' (Bachelor of Medicine, Medicinae Baccalaureus) and 'mb' is present in the answer.
'large' could be 'l' and 'l' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for emblazon that I've seen before include "Decorate with very bright design" , "Adorn with coat of arms" , "Depict (a heraldic device) on something" , "Decorate with colours or heraldic arms" , "Adorn strikingly" .)
