A third of Jewish Americans who did not grow up in New York have nonetheless been told that they sound like they're from that city. Sixty-eight percent of Reform Jews pronounce the word for the annual Jewish harvest festival "soo-COAT," as Israelis do, while only 34 percent use the Yiddish pronunciation "SUK-kiss"; among the ultra-Orthodox, those numbers are basically reversed.

These are just a few findings of the Survey of American Jewish Language and Identity, the results of which were published online by linguist Sarah Bunin Benor and sociologist Steven M. Cohen.

Instead of asking respondents how religious they are or whether their grandchildren will be Jewish, Benor and Cohen asked questions like, "When you say 'Mary' and 'merry' in regular speech, do they sound the same or different?" and "How do you refer to the Jewish skullcap?" By hitting the question of Jewish identity at a slant rather than head-on, the researchers have come up with an unusually nuanced portrait of contemporary American Jews.

"Patterns of language use can tell us things about identities and communities that might not even be known to the actors themselves," said Cohen, who has been conducting Jewish identity surveys of the more direct variety for some four decades. "There are things we can see through the side door that we can't see through the front door."

As Benor expected from her previous scholarship (like Cohen, she teaches at Hebrew Union College, the Reform movement's seminary, which sponsored the survey), the data suggests that for the most part, American Jews across the religious spectrum draw from the same "repertoire" of distinctive speech elements -- that is, they are English speakers who use varying amounts of Yiddish or Hebrew phrasing and grammar to distinguish themselves both from non-Jews and from Jews elsewhere on the spectrum. With the exception of those ultra-Orthodox Jews who use Yiddish as their primary language, Benor said, American Jews fall somewhere on this "continuum of distinctiveness" rather than being separable into different dialect groups.

"My favorite example is 'gmar cha-tee-MAH to-VAH,'" she said, enunciating each syllable of the traditional Yom Kippur greeting: in English, "may you be inscribed in the book of life." "That's the most modern Hebrew pronunciation you can get. Then there's 'gmar cha-TEE-mah TO-vah,' 'gmar cha-SEE-mah TO-vah,' and then 'gmar ch'SEE-mah TOY-vah." For those in the know, each pronunciation signifies a different spot on the religious continuum: a non-Orthodox Jew would probably use the modern Hebrew pronunciation; as you move along the spectrum of observance, the greeting becomes more Yiddish-inflected.

One of the key findings of the survey was what Benor and Cohen call "the growth of linguistic distinctiveness among the Orthodox." Distinctive strains of Yiddish-inflected English are not only still in everyday use among younger generations of Orthodox American Jews, their prevalence is growing.

Take the phrase, "She's staying by us," which borrows a Yiddish grammatical construction to mean, "She's staying at our place." Fifty-three percent of Orthodox Jews who took the survey use the phrase (versus 21 percent of non-Orthodox Jews).

But a full three quarters of Orthodox Jews between the ages of 18 and 24 use it, compared to 12 percent of Orthodox respondents 75 or older. According to the report, "such words and phrases are so important for Orthodox identity that many baalei teshuva (newly Orthodox Jews) make a conscious effort to incorporate them into their speech, even when some people consider them to be incorrect English."

Observant Sephardic and Mizrahi Jews -- whose ancestors never spoke Yiddish in the first place -- have adopted Yiddish religious terminology as well.

Benor attributes this to the fact that Orthodox communities have in general become more conservative, politically and culturally, in recent years. "Part of that shift to the right is a linguistic shift: some Jews who used to use less distinct English are now incorporating more Yiddishisms into their English," she said.

In non-Orthodox Jewish communities, two trends are happening concurrently, the survey found: as members of an older generation die and take certain language patterns with them, younger Jews are using more Yiddish and Hebrew than before (and certainly more than their more assimilationist parents' generation did).

But the words disappearing and those reappearing aren't necessarily the same words. Though Jews of all ages still say "shmutz" and "mazel tov," seniors are more likely than their grandchildren to use Yiddishisms like "haimish" (homey), "macher" (big shot), "nu?" (so?), "naches" (pride), and "bashert" (predestined).

Where the younger generation is overtaking their grandparents is with religious terminology -- Yiddish words like "shul," "daven," and "bentch" (for the blessing after meals).

"You see more Jews now identifying as a religious rather than as an ethnic group," Benor said. "Those Yiddish words that are increasing (in use) have to do with religious life." Thus, the phenomenon one survey respondent reported: "When I was growing up, I called it Temple. When my children went to Day School, I called it synagogue. I now call it shul. I am not sure why."

Though Jews across the religious spectrum said they would be likely to consider Hebrew names for their children, baby names are "an important resource for Jews to indicate intra-Jewish differences."

Less observant Jews, they found, are most likely to prefer anglicized biblical names, like Jacob, Ethan, Hannah, or Abigail. Modern Orthodox Jews were most likely to choose modern Hebrew names, like Ezra, Ari, Talia, or Eliana, often substituting them for the equivalent Yiddish names of deceased relatives (so, for example, they might name a daughter Tova, meaning "good" in Hebrew, after a grandmother named Gittel).

For the most part, only ultra-Orthodox Jews said they would consider giving a child a Yiddish name like Moyshe, Mendy, or Basya.

In one of the survey's least surprising findings, only two percent of Jews said they'd consider naming their baby Christopher.
