Sci-fi character almost upset the Force? (4)
I believe the answer is:
cops
'sci-fi character almost upset the force?' is the definition.
I can't tell whether this defines the answer.
'sci-fi character almost upset' is the wordplay.
'sci-fi character' becomes 'Spock' (Star Trek character).
'almost' means to remove the last letter (most of the word but not all of it).
'upset' says the letters should be written in reverse.
'spock' with its last letter taken away is 'spoc'.
'spoc' in reverse letter order is 'COPS'.
Can you help me to learn more?
(Other definitions for cops that I've seen before include "The police (sl.)" , "Panda owners" , "Police (slang)" , "Familiar American policemen" .)
