Drunk seamen screening Ken Loach film are coherent (4,5)
I believe the answer is:
make sense
'are coherent' is the definition.
I can't judge whether this definition defines the answer.
'drunk seamen screening ken loach film' is the wordplay.
'drunk' indicates anagramming the letters.
'screening' means one lot of letters goes inside another (inserted letters are covered or screened by others).
'ken loach film' becomes 'Kes'.
'seamen' is an anagram of 'maense'.
'maense' placed around 'kes' is 'MAKE SENSE'.
Can you help me to learn more?
(Other definitions for make sense that I've seen before include "Slaughterhouse" , "Be understandable or practicable - it's logical" , "Be intelligible" , "Add up" , "Be rational" .)
