Shakespeare’s first to reverence his justice (7)
I believe the answer is:
shallow
'justice' is the definition.
(I've seen this before)
'shakespeare's first to reverence his' is the wordplay.
I cannot quite see how this works, but
'first' could be 'low' (synonyms) and 'low' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for shallow that I've seen before include "Lacking depth" , "Without depth" , "Of waters, not deep" , "Insincere" , "incapable of serious thought" .)
