When I was young, it was more acceptable than it is today to mimic the speech of people who speak English with a recognizable accent. I remember that the stereotype of an Italian accent ended practically every-a word-a with the schwa sound-a. It's funny that I never questioned why, because none of the Italians I knew spoke like that.
Now I'm wondering if what the mimics were copying was not a generalized Italian accent, but specifically a Sicilian accent. That way of speaking was startlingly prevalent in our recent, and admittedly narrow, experience of Sicily. It marked the speech of our tour guide so strongly that a non-native speaking as she did would be accused of mockery.
I wrote the above when I documented our travel experiences; finally, my curiosity got the better of me and I decided to ask Claude about it. I'll skip the technical aspects of Claude's response, but the upshot is that I was right, though it's a feature not just of Sicily but of southern Italy in general. Italians from the more northern parts of Italy do not speak that way. Here's what Claude had to say about how it came to typify the "Italian" accent in America.
The overwhelming majority of Italian immigrants to the US between the 1880s and 1920s came from the Mezzogiorno — Sicily, Naples, Calabria, Campania — not from Tuscany or the north. The "Italian accent" that got absorbed into American pop culture (vaudeville, early film, later Chef Boyardee commercials and mob movies) was really a caricature built on Southern Italian and Sicilian-inflected English, filtered through immigrant communities in New York and elsewhere. It got flattened into "the" Italian accent in the popular imagination, even though it's specifically a regional feature.
It is as if all Americans were portrayed in foreign movies, commercials, and comedy shows as being from the Deep South, or maybe Brooklyn.
In the spirit of Trust but Verify, before posting I ran this through Gemini, which caught one typo and a couple of awkward sentences. (I reworded the latter, though not with Gemini's suggestions.) It also suggested the nuance that the "Italian accent" is present even in northern Italy, because the Italian language "favors...words ending in vowels. When native Italian speakers speak English, they naturally append a schwa to words ending in consonants to fit their native speech patterns." That makes sense, although I would say it is very much less marked in northern Italians.
