Exploitation of gasfield annoying people (8)
I believe the answer is:
gadflies
'annoying people' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'exploitation of gasfield' is the wordplay.
'exploitation of' indicates anagramming the letters (letters must be exploited or manipulated).
'gasfield' is an anagram of 'GADFLIES'.
Can you help me to learn more?
(Another definition for gadflies that I've seen is " Small insects that bite cattle and horses".)
