Play or take part in a tricky match (7)
I believe the answer is:
macbeth
'play' is the definition.
(I've seen this before)
'take part in a tricky match' is the wordplay.
'take part' becomes 'be' (being is a kind of taking. I am not sure about the 'part' bit.).
'in' means one lot of letters goes inside another.
'a tricky' is an anagram indicator.
'match' is an anagram of 'macth'.
'be' placed within 'macth' is 'MACBETH'.
'or' acts as a link.
Can you help me to learn more?
(Other definitions for macbeth that I've seen before include "Scottish ruler" , "Shakespeare's Scottish play, considered unlucky" , "Shakespears's Scottish play" , "its name must not be mentioned" , "He doth murder sleep (Shak.)" .)
