Synonym discussion

Sense: adjective/1

'Fixed', 'set', 'established', and 'predetermined' all describe something that is decided in advance, but they differ in tone and context. 'Fixed' is the most common and neutral word, used widely in everyday speech about prices, dates, and schedules — e.g. 'The rent is fixed at $800 per month.' 'Set' is very similar but slightly less formal; you might say 'a set menu' in a restaurant but 'a fixed price' in a contract. 'Established' implies that the arrangement has been in place for some time and is widely accepted, as in 'an established procedure' or 'an established rule'. 'Predetermined' is the most formal and technical, appearing in legal, scientific, or philosophical contexts where the outcome was decided by a prior cause or agreement. For a learner choosing among these, 'fixed' and 'set' are safe for most everyday situations, while 'established' adds the nuance of tradition, and 'predetermined' sounds precise and academic.

Etymology

LatinOld FrenchEnglish

The word 'fixed' comes from the Latin verb 'figere', meaning 'to fasten or attach'. This became 'fixer' in Old French, which meant 'to make stable or secure'. English borrowed 'fix' from French in the late 1300s, and by the 1500s 'fixed' was being used as an adjective meaning 'firmly placed'. The sense 'dishonestly arranged' dates from the late 1700s, originally in the context of boxing matches and horse races being secretly rigged. The veterinary sense emerged in American English around the mid-1900s, as a softer everyday term for spaying or neutering pets.
