What does atomisation mean?
Atomisation is the process of reducing something into very fine particles, droplets, or discrete parts. In its most concrete sense, it refers to turning a liquid into a fine spray — a technique essential to fuel injectors, aerosol sprays, spray painting, and medical inhalers, where breaking fluid into microscopic droplets improves efficiency and coverage. It can also describe the division of matter into individual atoms in scientific contexts. More figuratively, atomisation denotes the fragmentation of a society, community, or institution into small, isolated units, a usage frequent in sociological and cultural commentary on modern life. The word carries no strong emotional connotation itself; in technical writing it is neutral and precise, while in social criticism it often implies a loss of cohesion. Spelled 'atomization' in American English, it derives from the Greek atomos, meaning 'indivisible', and remains a valuable term wherever precision about scale matters — whether describing mist from a perfume bottle or the fraying of shared civic bonds.
nounThe act or process of breaking something down into very small particles or separate atoms. By extension, the reduction of something complex or unified into many small, disconnected parts.
- The physical process of converting a liquid into a fine spray or mist of tiny droplets, as in fuel injection, aerosols, or spray painting.
- The division of a substance into individual atoms or molecules.
- Figuratively, the fragmentation of a society, organisation, or body of knowledge into small, isolated units.
"Fuel injectors rely on the fine atomisation of petrol to ensure efficient combustion."
"Perfume bottles use atomisation to deliver fragrance as an even, fine mist."
"Critics argued that social media had led to the atomisation of public discourse into isolated echo chambers."
Your car's engine depends on it: without the atomisation of fuel into a fine mist, combustion would be hopelessly inefficient.

Etymology of atomisation
Atomisation derives from 'atom', which comes from the Greek atomos, meaning 'uncut' or 'indivisible' — the term ancient Greek philosophers gave to what they imagined were the smallest possible particles of matter. English formed the verb 'atomise' by adding the Latinate suffix -ise, and the noun followed as a regular deverbal formation in -ation. The word entered technical vocabulary during the nineteenth century as scientists studied gases, sprays, and the structure of matter, later extending metaphorically to social fragmentation.

How atomisation is actually used
Atomisation is chiefly used in technical and scientific contexts such as chemistry, engineering, and medicine, but its figurative sense — describing social or institutional fragmentation — has become common in sociology and cultural criticism. The spelling 'atomisation' with -s- is British; American English uses 'atomization'.
