Morphology
supervisor + call + instruction
The term is a transparent composition of 'supervisor' (the OS manager) + 'call' (an invocation) + 'instruction' (a machine command), so a learner who knows those constituent senses can infer it is an instruction that invokes the supervisor to request services. Although technical, the meaning follows regular compositional noun-modifier patterns common across languages and is therefore derivable from the parts.
Etymology
Supervisor call instruction is named like a worker asking the boss for help: the running program uses a small instruction to call the system supervisor when it needs a special job. The computer then pauses the program and lets the system do the work, so the phrase means 'ask the system for help'.
