Large group of countries screening Universal Soldier and Grease ? (9)
I believe the answer is:
lubricant
'grease ?' is the definition.
(I've seen this before)
'large group of countries screening universal soldier' is the wordplay.
'large' becomes 'L' (eg in clothes sizes).
'group of countries' becomes 'bric' (I can't explain this - if you can you should believe this answer much more).
'screening' indicates putting letters inside (inserted letters are covered or screened by others).
'universal' becomes 'U' (film certificate).
'soldier' becomes 'ant' (soldier is a type of ant).
'l'+'bric'='lbric'
'lbric' going around 'u' is 'lubric'.
'lubric'+'ant'='LUBRICANT'
'and' is the link.
Can you help me to learn more?
(Other definitions for lubricant that I've seen before include "it has a smoothing effect" , "Substance reducing friction" , "E.g. oil" , "Oil, for example" , "Oil or grease" .)
