Poll So this isn't completely out-of-the-blue, the back story:
Ya lives, ya learns. I always thought Piet Mondrian went by his French name, not the original Dutch. His first name is pronounced Pete, according to all sources I've found. Colour me under-educated, I suppose. [Even worse, I misspelled Mondrian! For shame. Sigh.]
In Canadian English, "decal" ends in "-kl" not "-kal" as it seems to elsewhere. This didn't come up in the five years we've lived here, until yesterday at the parking office. I was... a bit surprised. It was clear what she meant, and I didn't laugh at her "mispronunciation", but I was surprised when I looked it up and found out this is one of those things that's different here.
Anyhow, I was amused. :)
