What does atomise mean?
Atomise means to reduce something to extremely small particles or droplets — literally, as when a fuel injector breaks petrol into a fine mist for efficient burning, or when a device converts liquid perfume into a spray. The word also has a powerful figurative use: societies, workforces, and institutions can be described as atomised when they fragment into disconnected individuals who have lost cohesion and collective identity, a sense common in social and political commentary with a distinctly negative connotation. The verb derives from 'atom', ultimately from the Greek atomos, meaning 'uncuttable' or indivisible. Spelled 'atomise' chiefly in British English and 'atomize' in American English, it takes related forms such as atomisation and atomiser. It should not be confused with anatomise, which refers to detailed dissection or analysis rather than physical reduction to particles.
verbTo atomise is to reduce something to fine particles or droplets, or, figuratively, to break a whole into tiny, disconnected fragments or to destroy something utterly.
- To convert a liquid into a fine spray or mist of tiny droplets (technical/scientific sense).
- To break something into very small pieces or particles.
- Figuratively, to fragment a group, institution, or concept into isolated parts, or to destroy something completely.
"The engine's fuel injectors atomise petrol into a fine mist before combustion."
"Perfume atomisers work by forcing liquid through a tiny nozzle at high pressure."
"Critics argued that gig-economy working practices had atomised the workforce, leaving employees isolated and unorganised."
The same word that describes your car's fuel injector also describes how modern life can shatter communities into isolated individuals — physics and sociology in one verb.

Etymology of atomise
Atomise derives from 'atom', which comes from the Greek atomos, meaning 'indivisible' or 'uncuttable' (from a- 'not' + tomos 'a cutting'). The noun entered English via Latin and French, and the verb formed in the 19th century alongside advances in chemistry and physics that made the atomic theory central to science. Cognates sharing this root include atomic, atomism, and anatomy (which preserves the underlying Greek idea of 'cutting up').

How atomise is actually used
Chiefly British spelling; American English typically uses 'atomize'. The literal sense is common in science and engineering (combustion, spraying); the figurative sense carries a negative connotation of fragmentation and isolation, especially in social commentary. Both '-ise' and '-ize' spellings are acceptable in British English, with '-ise' more traditional.
Easily confused with atomise
'Anatomise' means to dissect or analyse in minute detail (from Greek anatome, 'cutting up'), while 'atomise' means to reduce to particles or fragments — they share a root but differ in meaning.
