Vigour I am contributing to a country (9)
I believe the answer is:
animation
'vigour' is the definition.
(animation can mean vigour or vitality)
'i am contributing to a country' is the wordplay.
'i am' becomes 'I'm' (contraction).
'contributing to' is an insertion indicator (inserted letters make a new contribution).
'country' becomes 'nation' (synonyms).
'a'+'nation'='anation'
'im' going into 'anation' is 'ANIMATION'.
(Other definitions for animation that I've seen before include "Cartoon-making art" , "Liveliness and vigour" , "Liveliness and enthusiasm" , "Making of cartoons" , "Film technique; lively state" .)
