Morphology

OS = operating + system (semi-transparent) = O + S

The form is an acronym formed from the initial letters of 'operating system'; knowing those base words makes the meaning clear. [Postprocessing: changed transparency from 'transparent' to 'semi-transparent' for abbreviation]

Etymology

OS is short for operating system, where operating means 'working' and system means 'a set of parts that work together', so an OS is the main software that runs and controls a computer.
