Synonym discussion
Sense: adjective/1
All four words describe things that are no longer used, but they differ in emphasis. 'Disused' specifically refers to buildings, railways, or infrastructure that were once actively used and have fallen out of use — the focus is on the cessation of activity. 'Abandoned' carries the sense that people deliberately left the place with no intention of returning; it often suggests neglect and possible danger. 'Derelict' goes further, implying physical decay and damage — a derelict building may have broken windows and collapsed roofs. 'Unused' is neutral: it simply means something is not currently in use, without any history of prior use or abandonment. Finally, 'deserted' describes a place where people have suddenly left, making it feel empty and lonely. For example, a factory that stopped operating five years ago is 'disused', but if vandals have wrecked it, it becomes 'derelict'. A spare bedroom with fresh paint is 'unused' but never 'disused'.

Etymology
Formed in English by adding the prefix 'dis-' (from Latin, meaning 'not' or 'the opposite of') to the past participle 'used'. The base word 'use' entered English through Old French 'user', which came from Latin 'ūtī' (to use, to employ). The word 'disused' emerged in the 1500s to describe something that is no longer employed for its original purpose.
