Etymology: Aerosolisation is a modern technical coinage built from "aerosol" plus the suffix "-isation," so its story is really the story of its two parts. "Aerosol" joins the Greek "aēr," meaning air, which gave the English combining form "aero-," with "solution," borrowed from Latin "solutio" through Old French. The "-ise" and "-ation" endings were added to turn that noun into a verb and then a noun of action, so the word names the process of making a substance into an aerosol. The sense of the whole is therefore literal: the word describes the act of dispersing a liquid into fine airborne droplets, the mist that spray cans, inhalers and nebulisers produce. Nothing in its ancient roots anticipated that meaning, since the Greek and Latin elements were available to English speakers long before anyone needed a single term for atomising liquids into gas.
