The Oxford English Dictionary has announced its word of the year for 2021:-
Vax
A new 3-letter-word for Scrabble players! A shame they didn't make it Vaxx - double x would be worth a lot of points.
For some reason, double-vaxxed, unvaxxed and anti-vaxxer have also increased in use over the past 12 months.
I don't say I am double-vaxxed, I tell people I am double-chipped, just to see the look on their faces.
