A fast-growing slang word among members of Generations Z and Alpha - both online and in everyday conversation - mogging went mainstream in 2026 with a 210% increase in its usage.
Collins' English Dictionary managing director Alex Beecroft said its lexicographers look at "how often words are used" and also "analyse patterns of usage" that reveal the latest linguistic trends.
