If you've been getting this one wrong, then maybe it's time to think about picking up some new prescription glasses. See what we did there? How did you pronounce that word in your head when you read it? Just like the word 'espresso' before it at number five, 'prescription' doesn't have any fancy tricks to it - it is pronounced exactly as it is spelled, too.
There's something about the human brain that sometimes messes with words that start 'pre' and spins the 'r' and the 'e' around for us before the sound comes out of our mouths. If you want your doctor to write a note for you so you can pick up some medication, then what you're looking for isn't a "pur-script-shun". This is another word that's said exactly as it's spelled, and it's "pre-script-shun".
