Morphology

CRT = cathode + ray + tube (opaque) = C + R + T

Formed as an initialism from 'cathode ray tube'; the connection to the expanded phrase is direct but requires knowing the expansion.

Etymology

CRT stands for cathode, ray, and tube; it names a big glass tube that sent a stream of 'rays' to light a glowing screen, which is why old TVs and computer monitors with a CRT were heavy and deep.
