Lots and lots of writing on the various wars (6)
I believe the answer is:
swarms
'lots' is the definition.
The definition and answer can be both groups as well as being plural nouns.
Maybe you can see an association between them that I don't see?
'lots of writing on the various wars' is the wordplay.
'lots of' means to remove the last letter (the majority of the word).
'writing' becomes 'mss'.
'on' is a charade indicator (letters next to each other).
'the various' indicates anagramming the letters.
'mss' with its last letter taken away is 'ms'.
'wars' with letters rearranged gives 'swar'.
'ms' put after 'swar' is 'SWARMS'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for swarms that I've seen before include "Dense groups of flying insects" , "Large groups of flying bees" , "'Moving crowds, of bees say (6)'" .)
