Two major dictionary publishers have chosen pandemic as the 2020 word of the year. Merriam-Webster and Dictionary.com both declared their choices on Monday. Merriam-Webster said its decision was based on the “extremely high numbers” of people who had looked up pandemic in its online dictionary in 2020. The word showed a major year-over-year increase in internet traffic, the company said. The World Health Organization (WHO) declared COVID-19 a pandemic on March 11. The Merriam-Webster Learners’ Dictionary defines pandemic as an occurrence in which a disease spreads very quickly and affects a large number of people over a wide area or throughout the world. Searches for pandemic on the Merriam-Webster website rose more than 115,000 percent on March 11 compared to a year earlier.
