=solid-state
solid + state = the solid state of matter. Here state means a physical condition (solid vs liquid vs gas) — the st root sense of 'how a thing stands/is set.' Solid-state electronics rely on solid semiconductors instead of glowing vacuum tubes, hence SSD = solid-state drive.
Why It Means This
A nice reminder that state isn't only political. The st root underlies 'state of matter': solid, liquid, gas are the ways matter 'stands.' Solid-state tech replaced fragile moving/heated parts with stable solid chips.
