Combining money, resources, or efforts with other people to work toward a shared goal.
From 'pool' (originally a betting term from French 'poule', a chicken or pot of money), plus '-ing'. The term became common for shared resources by the 1800s.
The word 'pool' as a shared resource comes from old gambling games where everyone would contribute money into a 'pot' called a 'poule'—so you're literally gambling together, which explains why pooling resources feels like cooperation!
