Other forms: contributions
When you make a contribution, it means you're giving something away — whether it's your money, your possessions, or your time.
A contribution can take many forms. Some contributions are measurable, like a $10 donation to the Salvation Army. Others are less tangible. When a student raises his hand in class to ask a question, he's making a contribution, because the answer to his question enriches the other students' learning experience.
