As a non-native English speaker, I just realised that I have probably been pronouncing the word "national" wrong for 20+ years.
I have been pronouncing the "t", kind of like "nat-shoe-null" (but of course as one word :)
I didn't believe it when someone told me it's pronounced "na-shoe-null", so I had to look it up. And sure enough — none of the videos I could find pronounce the "t". Both British and American English. I was shocked.
I'm sure I've heard people say it all the time in movies, Youtube videos, etc., so now I'm really confused - do native English speakers ever pronounce the "t", or have I just been imagining it (perhaps with some help of confirmation bias)?
