Brandish weapon and even detain actor at The Globe (13)
I believe the answer is:
shakespearean
'even detain actor at the globe' is the definition.
I can't judge whether this defines the answer.
'brandish weapon and' is the wordplay.
I cannot really see how this works, but
'brandish' could be 'shake' (I've seen this in another clue) and 'shake' is found in the answer.
'weapon' could be 'spear' (spear is a kind of weapon) and 'spear' is located in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
The remaining letters 'ea' 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).
Can you help me to learn more?
(Other definitions for shakespearean that I've seen before include "Student of the Bard" , "Water" .)
