I don’t get it.
It’s a city in southern Arizona and also the name of a particular Hyundai model. Hope that helps.
If pronounced like it’s spelled, it should be TUCK-sen or TOOK-sen.
This might provide some background.
We should get together for Happy Hour on a patio somewhere in Tucson.
I need to get two tutus to Tucson by Tuesday…
If it’s son then that’s a relatively hard stop in the pronunciation, and Americans don’t have time for that.
I’m sure there’s words in the English language where “son” is pronounced sen but I’m an actuary, not a vocabulary expert.
