An extract from a film showing this kind of joint (4)
I believe the answer is:
clip
This clue could be a double definition.
'an extract' is the first definition.
(thesaurus)
'a film showing this kind of joint' is the second definition.
'clip' can be an answer for 'kind of joint' (I've seen this in another clue). I'm not sure about the rest of the definition.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for clip that I've seen before include "part for one that's the bulldog type?" , "rate" , "Short piece of film" , "speed" , "Trim, hedges perhaps" .)
