A project is a piece of work that is planned or intended. Plan a little extra time for your gingerbread house project — gluing the walls and roof can take a while.
If you call a person your project, pronounced PRAH-jekt, it means you are trying to improve them by telling them how to behave, etc. As a verb, pronounced pro-JEKT, it means to jut out literally — The fireplace projects into the dining room — or figuratively — Try to project your ideas forcefully. If you assume another person is feeling the same things you are, you are projecting you feelings onto them.
