A former PM's caught hit for six (5)
I believe the answer is:
amaze
'a former pm's caught hit for six' is the definition.
I can't tell whether this defines the answer.
'a former pm's caught' is the wordplay.
'former pm's' becomes 'May's' (former UK prime minister Theresa May).
'caught' shows a homophone (sound like) (heard).
'mays' is a homophone of 'maze'.
'a'+'maze'='AMAZE'
Can you help me to learn more?
(Other definitions for amaze that I've seen before include "Greatly surprise in a labyrinth" , "Bowl over" , "Greatly surprise, fill with wonder" , "Greatly surprise, astound" , "Affect with wonder" .)
