What does system mean?
A system is an organized arrangement of parts, rules, or processes that work together to perform a function or achieve a purpose. The word applies broadly: a country may have a political or economic system, the human body has interconnected systems, and a computer depends on an operating system to coordinate its software and hardware. In general use, “system” suggests structure and coordinated organization rather than a single isolated object. It can also refer to an established framework of ideas, such as a philosophical or scientific system. The term is common in formal, educational, technical, and institutional contexts, and it often implies that relationships among the parts are deliberate and intelligible. Although “system” can occasionally be used negatively, as in bureaucracy or a malfunctioning system, its usual connotation is neutral or favorable, emphasizing order, efficiency, and organization.
An organized set of related parts, rules, or processes that function together; also, a computing environment or coordinated set of hardware and software.
"The proposed tax system would change how local governments finance public services."
The sense “an organized arrangement” is the most general. In computing, “system” commonly refers to an operating system or a coordinated collection of hardware and software.
To organize or arrange something according to an ordered plan or systematic method.

This verb is uncommon compared with the noun and is most often found in formal or technical writing.
The standard plural is used for organized arrangements, institutions, computing environments, and other independent instances.

From Greek, system meant an organized whole: even the word’s everyday sense still carries the idea of parts working together in a planned structure.

Etymology of system
The word comes from Latin systema, borrowed from Greek systēma, meaning an organized whole. Greek systēma was formed from systein, “to put together,” and related to syn- and -stēma, associated with standing or placing together. Latin systema entered English through scientific and philosophical writing and developed its modern senses through organized classifications, institutions, and mechanical arrangements.
