A few days ago T used this phrase while we were chatting in the car eating KFC as we drove up the A34. I corrected his pronounciation, 3 syllables, not 2. Then I pointed out that I had never said it myself until right then, nor had I ever heard anyone, child or adult use it in conversation either, so I could be wrong about how to say it.
That is home education. Experimenting with a new phrase, wondering about how to say it, pointing out that it is Latin. So what that it was on the way home from his school. He chooses to go there, mind you at age 11 it was a choice of several schools, I didn't offer HE as an option back then. He knows it is an option now.
