What exactly does Gibbs Free Energy measure?

It measures the energy that is freely available to do work.

The textbook defines Gibbs free energy as the energy of a system that is free to do work at constant temperature and pressure. The direction of spontaneous change at constant pressure and temperature is the direction of decreasing Gibbs free energy.

I think that Gibbs free energy isn't necessarily a measurement, but a calculation to describe the energy of a system available to do work based on a system's entropy, enthalpy, and temperature. I believe Professor Lavelle mentioned in class you can't explicitly measure free energy-just to clarify. Hope this helps!
