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 tell whether this defines the answer.
'drunk seamen screening ken loach film' is the wordplay.
'drunk' is an anagram indicator.
'screening' is an insertion indicator (inserted letters are covered or screened by others).
'ken loach film' becomes 'Kes'.
'seamen' with letters rearranged gives '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" .)
