Growing up in the Central Valley, I found that most people pronounced it this way unless they were growers or part of the farm community that had growers in it. Then it was “ammin(d)” where the a is pronounced like the a in “have”, the i is pronounced like the i in pin, and the d is sometimes at the end and sometimes not.
Yes, Germans too. It’s also the name of a brand for wall paint, Alpina Weiß. The German word for the adjective “alpine” is “alpin”, also pronounced “al-peen”.
Yeah. IME in the grower community “almond” sounds exactly like the standard pronunciation of “famine” (= widespread food shortage) just without the “f” on the front.
