Etymology

Origin of association

First recorded in 1525–35; from Middle French, from Medieval Latin associātiōn-, stem of associātiō “accompaniment, unification”; equivalent to associate + -ion

Explanation

Association has to do with things that are together, whether in a formal group like the National Basketball Association or just two things that are related, like the association between dogs and parks. Any time people or things are connected, there are associations. The National Basketball Association is an example of the business meaning of association — a formal organization or group that works together. If you ask, "What is your association with Bill?" That just means, "How are you connected to Bill?" You can also make mental associations — you might make an association between the smell of fresh bread and your grandmother's kitchen, for example.
