CHIP-IN/CHIP IN.

The phrase "chip in" means to contribute-whether money, time, or effort-toward a shared goal or project.
One possible origin comes from golf, where "chip-in" refers to a shot played from off the green that lands close to the hole. This shot is typically made with a highly lofted club to control the ball's trajectory and accuracy.
Another likely source is poker and other card games, where "chip in" means to place chips as a bet to stay in the game.
Key Differences:
Chip in (verb) - To contribute or participate.
Chip-in (noun) - A golf term for a shot that gets close to the hole from off the green.
Over time, the meaning of "chip in" has expanded beyond its original contexts, becoming a widely used expression for contributing to various situations.
Examples:
We all chipped in to raise money for the foundation.
If we all chip in, this project could be finished by Friday.
If you have questions or want to chip in, go ahead. This is an open discussion.
