Opening of cinema features parts of films (5)
I believe the answer is:
clips
'films' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'opening of cinema features parts' is the wordplay.
'opening of' says to take the initial letters.
'features parts' becomes 'lips' (I am not sure about this - if you are sure you should believe this answer much more).
The initial letter of 'cinema' is 'c'.
'c'+'lips'='CLIPS'
'of' is the link.
Can you help me to learn more?
(Other definitions for clips that I've seen before include "Cuts; fasteners" , "Trims" , "reduces" .)
