Synonym discussion
Sense: noun/1
All four words refer to a collection of people with a shared purpose, but they differ in formality and scope. 'Group' is the broadest and most neutral term — it can describe three friends meeting for coffee or a department within a large company. 'Organisation' implies a formal structure with rules, leadership, and defined goals; it is the most natural choice for businesses, charities, and clubs. 'Institution' suggests a long-established organisation with a recognised role in society, such as a university or a central bank — it carries more weight and permanence than 'organisation'. 'Association' typically refers to a membership-based group that exists to promote a shared interest or profession, like 'the British Medical Association'. 'Body' is a formal synonym often used in official contexts, such as 'a regulatory body' or 'the student representative body'. For everyday use, 'organisation' is the best fit for most formal groups; use 'group' for informal collections, and reserve 'institution' for historically significant or large-scale entities.

Etymology
The word 'organisation' entered English in the 15th century from Old French 'organisation', which came from Latin 'organum' meaning 'instrument' or 'tool'. The root goes back to Greek 'organon' (εργανον), also meaning a tool or instrument. The idea of a structured body — like a tool made of fitted parts — gave rise to the modern sense of a group of people working together as a coordinated whole. The spelling 'organisation' is standard in British English, while American English prefers 'organization'.
