Language changes, and has always changed. It’s helpful to think of language as a living thing, that evolves and changes as the need arises. We still speak English, but it’s not like the English of Shakespeare’s time, or English in 1776. New words appear every year in both Merriam-Webster’s and the Oxford English Dictionary, and sometimes the addition of a word can be controversial. People feel very strongly about making a slang word “official,” but I would argue that we should embrace language changes. (I’m not arguing that you need to adopt words into your daily lexicon that you don’t like, just maybe don’t feel anger over a new word.)
2020 added a lot of new words and phrases to our daily conversations. “Social distancing”, “COVID-19”, “community spread”, “herd immunity”, and the abbreviation “WFH (work from home)” were all added to Merriam-Webster’s Dictionary in 2020.
