Stirrers from Costa no cost -- gratis to put another way (9)
I believe the answer is:
agitators
'stirrers' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'costa no cost gratis to put another way' is the wordplay.
'no' suggests deleting specific letters.
'put another way' indicates anagramming the letters (letters arranged a different way).
'costa' with 'cost' removed is 'a'.
'gratis'+'to'='gratisto'
'gratisto' is an anagram of 'gitators'.
'a'+'gitators'='AGITATORS'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for agitators that I've seen before include "revolutionaries" , "A gait rots the stirrers" , "Rabble-rousers" , "We wind up" .)
