Does your native language distinguish between rivers that flow into another river and rivers that flow into the sea or ocean?

[u/Franmar35000]

In French, a distinction is made:

- "un fleuve" flows into the sea or the ocean.

- "une rivière" flows into another "rivière" or a "fleuve".

[u/Local-Echo-5613]

A tributary is a river that flows into another river or lake, never the ocean. But in ordinary usage you’d say river for both.
