Minor figures in international body engaged in much oil wrangling (9)
I believe the answer is:
homunculi
'minor figures' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'international body engaged in much oil wrangling' is the wordplay.
'international body' becomes 'UN' (short for United Nations).
'engaged in' means one lot of letters goes inside another.
'wrangling' is an anagram indicator (wrangle can mean to round up and organise).
'much'+'oil'='muchoil'
'muchoil' with letters rearranged gives 'homculi'.
'un' inserted into 'homculi' is 'HOMUNCULI'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for homunculi that I've seen before include "little people!" , "Small humanoid creatures" .)
