In Calais, I start to arouse terrible envy (8)
I believe the answer is:
jealousy
'envy' is the definition.
(jealousy is a kind of envy)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for jealousy that I've seen before include "Envious emotion" , "Covetousness - envy" , "Suspicious resentment" , "Envious resentment" , "Form of resentment" .)
