Seen working round about, in peace (6)
I believe the answer is:
serene
'seen working round about in peace' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs can sometimes mean the same thing.
'seen working round about in' is the wordplay.
'working' is an anagram indicator.
'round' says the letters should be written in reverse.
'about' becomes 're' ('re' means regarding or about).
'in' is an insertion indicator.
're' in reverse letter order is 'er'.
'seen' anagrammed gives 'sene'.
'sene' going around 'er' is 'SERENE'.
Can you help me to learn more?
(Other definitions for serene that I've seen before include "Calm, untroubled" , "Placid" , "still" , "Calm and unruffled, like a princely title." , "Calm and at peace" .)
