Each year the Australian National Dictionary Centre, based at the Australian National University (ANU), selects "a word or expression that has gained prominence in the Australian social landscape". In 2020, "iso" took out first place, with "bubble" following close behind. On the Centre's website, Senior Researcher Mark Gywnn explains that "iso" was selected not only for its flexibility, merrily combining with other words to create new compound words (for instance "being in iso", doing "iso baking" and putting on "iso weight"), but also because it "stood out asa characteristically Aussie abbreviation" (Australian National Dictionary Centre).
