Where two streams join at a point is called?

When a smaller river joins a larger river, it is called a tributary. Tributaries do not join lakes, seas, or oceans directly, but first meets another river.

----------------------------------

When two rivers of roughly equal size join, that can be called a confluence.

If you were Cherokee, you might call it tanasi, a Word applied to the place where rivers now know as the Holston and French Broad flow together. White settlers altered the Word into Tennessee, a name applied to the river downstream from that confluence, and later to the state.

- You dont need to waffle on like that, its a tributary - for anyone who dosent want to read the above
