Here are some examples:
* Demi-god: A being who is partly god and partly human.
* Demi-monde: A group of people considered to be on the fringes of society.
* Demi-tasse: A small cup of coffee, literally "half cup."
* Demi-john: A large glass bottle with a rounded body and a narrow neck.
The meaning of "demi-" can sometimes vary depending on the context. For example, "demi-season" refers to a period of time between seasons, not necessarily half a season.
