Is not organised by the people one speaks of (8)
I believe the answer is:
mentions
'one speaks of' is the definition.
I can't judge whether this defines the answer.
'is not organised by the people' is the wordplay.
'organised' indicates an anagram.
'by' means one lot of letters go next to another.
'the people' becomes 'men' (men are people).
'is'+'not'='isnot'
'isnot' anagrammed gives 'tions'.
'tions' after 'men' is 'MENTIONS'.
Can you help me to learn more?
(Other definitions for mentions that I've seen before include "Refers to briefly" , "Makes reference to sonnet I'm changing" , "Names" , "Points out" , "Touches on" .)
