Plant spies to pursue leaders of agitators, communists and anarchists (6)
I believe the answer is:
acacia
'plant' is the definition.
The answer is an example.
'spies to pursue leaders of agitators communists and anarchists' is the wordplay.
'spies' becomes 'cia' (Central Intelligence Agency).
'to pursue' is a charade indicator (letters next to each other).
'leaders of' suggests taking the first letters.
'and' is a charade indicator (letters next to each other).
'anarchists' becomes 'a' (this might be a standard abbreviation which I don't know about).
The initial letters of 'agitators communists' is 'ac'.
'ac'+'a'='aca'
'cia' put after 'aca' is 'ACACIA'.
Can you help me to learn more?
(Other definitions for acacia that I've seen before include "Locust tree the false one" , "Spiny shrub with clusters of yellow or white flowers" , "Tree or shrub with yellow or white flowers" , "Australian tree" , "Spiny tree of warm climates" .)
