join
Pluraljoins
- 1To become a member of a group, organization, or body.
Hundreds of volunteers join the charity every spring.
He joined the local orchestra as a second violinist.
UsageNo preposition before the group: join the army, join a club (not
incorrect: join to a club).Note
Membership is the everyday use, and the object can drop away when the group is already clear. In W. B. Maxwell's The Mirror and the Lamp (1918), a union is started for the laborers and "all but a few joined." Children join a club, politicians a party: the verb marks the moment of entry, not the lasting state of belonging.

Note
Network administration turns the verb into a noun for the event of connecting: a device performs a join, and a join can succeed or fail. The noun combines freely with what is joined. Dustin Hannifin's Microsoft Windows Server 2008 R2 Administrator's Reference (2010), for instance, describes "the offline domain join" as a three-step process.

- 9A database operation, or its result, that combines rows from two or more tables, usually by matching values in related columns.
The query used a join across the orders and customers tables.
Each additional join increased the report's running time.
Note
Here the matching done by the database verb becomes a countable thing. A query can contain one join or several, each named by the tables it spans, as in a join across the orders and customers tables. Because joins can ask the database to do more matching, each one added can lengthen a report's running time.
