A tithe is a tenth part of something, usually money or crops, given as an offering to help others.
When people think of tithing, they often connect it with churches and charities. Some people give a tenth of their income to their church or favorite cause, while others donate food or goods to local organizations. The idea is that by giving a small portion of what you have, you're showing your support for the community and helping those in need. It's a way of sharing what you have with others, even if it's just a small part of it.
How common is "tithe"?
