There isn't really a single "other name" for liquid. It's a fundamental state of matter, and its name is pretty well established! However, you could use some of these terms depending on the context:

* Fluid: This is a general term for anything that can flow, including liquids and gases.

* Fluid phase: This emphasizes that it's one of the phases of matter, along with solid and gas.

* Liquid state: Similar to "fluid phase," but specifically highlighting its state.

Ultimately, the best alternative depends on the specific situation and what you're trying to emphasize.
