Welcome to the Wordlady blog!

This blog is about the fascinating, fun, and challenging things about the English language. I hope to entertain you and to help you with problems or just questions you might have with spelling and usage. I go beyond just stating what is right and what is wrong, and provide some history or some tips to help you remember. Is something puzzling you? Feel free to email me at wordlady.barber@gmail.com.
You can also order my best-selling books, Six Words You Never Knew Had Something to do With Pigs and Only in Canada You Say. Fun and informative!

No flora in your lightbulbs or toothpaste

Two related words which are very commonly misspelled are "fluorescent" and "fluoride". Don't forget the "U". Fluorescence and fluoride have nothing to do with flowers. They're derived from a mineral, fluor, called that because it is easily melted and thus fluid.
