Fun little quiz on whether you can guess the 100 most common words in the English language in 5 minutes. I got 46, and that was with Duncan helping. I don’t do well under pressure, I tend to freeze up. So, despite the fact that I’m a primary school teacher and should know these words, I sort of was very little use in this exercise and Duncan was struggling along standing behind me giving me suggestions while I stared blankly. Hahaha. I hate time trials. But it’s fun anyway.
