Still show resistance for second time (2,4)
I believe the answer is:
at rest
'still' is the definition.
(synonyms)
'resistance for second time' is the wordplay.
I cannot quite understand how this works, but
'resistance' could be 'r' (electronics abbreviation) and 'r' is found within the answer.
'second' could be 's' (common abbreviation) and 's' is found in the answer.
'time' could be 't' (abbreviation) and 't' is located in the answer.
This explanation may well be incorrect...
'show' is the link.
(Other definitions for at rest that I've seen before include "Not moving, free from anxiety" , "Not moving, free from trouble - maybe dead" , "Stopped" , "Still" , "Motionless" .)
