I believe the word "coup" is an abbreviation. Do Americans use the full term of "coup d'état" on formal occasions?

You're right, the word "coup" is a shortened version of the French word "coup d'état", which refers to a sudden enforcement or seizure of power from a government. However, Americans never use the full French word and only ever use the word "coup" to refer to this word.
