Very good policeman on beat, initially (6)
I believe the answer is:
superb
'very good' is the definition.
'superb' can be an answer for 'good' (thesaurus). I am not sure about the 'very' bit.
'policeman on beat initially' is the wordplay.
'policeman' becomes 'super' (short for superintendant).
'on' means one lot of letters go next to another.
'initially' says to take the initial letters.
The initial letter of 'beat' is 'b'.
'super'+'b'='SUPERB'
Can you help me to learn more?
(Other definitions for superb that I've seen before include "Impressively splendid" , "Of surpassing excellence" , "Terrific" , "First class" , "Dazzling" .)
