but what is an eutectic?

Eutectics don't have to have specific phases at the point.

"Eutectic point" is generally defined as "the lowest melting point for
any alloy."

A eutectic alloy is an alloy of a composition that has the lowest melting
point of related alloys.
This composition is the eutectic composition.
The temperature at which it solidifies is the eutectic temperature.
The combination of composition and temperature is the eutectic point.
