Man entering state of unconsciousness — indicator of a pause (5)
I believe the answer is:
comma
'indicator of a pause' is the definition.
'comma' can be an answer for 'pause' (I've seen this before). I am not sure about the 'indicator of a' bit.
'man entering state of unconsciousness' is the wordplay.
'man' becomes 'm'.
'entering' indicates putting letters inside.
'state of unconsciousness' becomes 'coma' (I've seen this before).
'm' placed inside 'coma' is 'COMMA'.
Can you help me to learn more?
(Other definitions for comma that I've seen before include "Common punctuation park" , "part of list, invariably" , "identifying place to breathe" , ", (stet)" , "Punctuation mark - butterfly" .)
