Morphology
gas-discharge + tube
The compound is fully compositional: 'gas' + 'discharge' + 'tube' denotes a tube in which a discharge occurs in a gas, so a learner who knows those words can infer it refers to a device where electrical discharge passes through gas. It is a standard noun‑noun technical naming pattern (cross‑linguistically common), so despite some specialized details (sealed, electrical), the core meaning is predictable from the constituents.
Etymology
Gas-discharge tube comes from a simple image: a glass tube full of gas where an electric discharge, 'a sudden flow of electricity', jumps through the gas and often makes light. So the name simply describes what it is: a tube where gas lights up when electricity is released.
