Taking a rest from veracity (5)
I believe the answer is:
lying
'taking' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'a rest from veracity?' is the wordplay.
I cannot really understand how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for lying that I've seen before include "Duplicity" , "Prone - mendacity" , "retailing pork pies" , "Invention" , "Not straight" .)
