Fettuccine vs. Fettuccini: Why Italian Spelling Matters (And When It Doesn’t)

The question seems simple but reveals something fascinating about how language works: Is it fettuccine or fettuccini? The answer is both are used, but linguistically, only one is correct—at least in Italian. Understanding the difference tells us something important about how words travel between languages and what “correct” actually means.

The Italian Rule: Gender and Plurals

In Italian, fettuccine is the correct plural form. Here’s why: fettuccine is the plural of the feminine noun fettuccina, which is itself a diminutive of fettuccia, literally meaning “ribbon.” In Italian grammar, feminine plurals end in -e, while masculine plurals end in -i. Since fettuccina is feminine, its plural must be fettuccine, not fettuccini.

This is not a suggestion or a convention—it’s a grammar rule with no exceptions in standard Italian. If you wanted to spell the word out loud to an Italian speaker, you would pronounce each letter: “f-e-t-t-u-c-c-i-n-e,” ending with the “eh” sound you hear in the English word “bread,” not the “ee” sound in “teeth.”

How Pronunciation Reveals the Difference

The mispronunciation in English often comes from how we hear “fettuccini.” In Italian, the final -e is pronounced with an open, relaxed vowel sound (like “eh”), not the closed “ee” sound that English speakers tend to add. When English speakers say “fettuccini,” they’re often unconsciously shifting to the masculine plural ending and the English “ee” pronunciation that feels more natural to them.

Interestingly, this mispronunciation has become so standard in English that it’s now considered correct by most English speakers, even though it’s not actually correct in Italian.

When Words Cross Borders: The Zucchini Precedent

Fettuccine is not alone in this journey. Consider zucchini, which perfectly illustrates what happens when Italian words are adopted into English. In Italian, the vegetable exists in multiple forms:

Feminine: zucchina (singular), zucchine (plural)
Masculine: zucchino (singular), zucchini (plural)

English speakers adopted zucchini—the Italian masculine plural—and used it as a singular noun. The adoption has been so complete that English speakers now even pluralize it as “zucchinis,” which would have no grammatical meaning in Italian. As English integrated the word, it didn’t follow Italian grammar rules; instead, English treated it as an English word and applied English pluralization patterns.

This is what linguists call loanword adaptation. Languages don’t just borrow words; they adapt them to fit their own grammatical systems. Fettuccini is currently undergoing this same transformation in English.

So Should You Use Fettuccine or Fettuccini?

It depends on context and your goals:

In formal or authentically Italian contexts (a restaurant menu claiming Italian authenticity, a food blog emphasizing Italian cuisine), use fettuccine. It signals that you understand and respect the language and culture behind the dish. Italian diners will notice.
In casual English contexts (everyday conversation, casual restaurant ordering, informal recipes), fettuccini is so standard that using the Italian form might actually seem affected to other English speakers.
The practical reality: English is absorbing fettuccini just as it absorbed zucchini. Language purists can object, but once millions of English speakers settle on a spelling, that spelling becomes part of English, even if it’s “wrong” by Italian standards.

The Bigger Picture: Why This Matters

This isn’t really about getting a word “right.” It’s about understanding that language is a system, and systems change when they cross cultural boundaries. Italian spelling has strict rules and no exceptions—except for borrowed words. English is more flexible and adopts loanwords more freely, reshaping them as needed.

If you care about honoring the dish’s origins, use fettuccine. If you’re writing for an English audience in a casual context, fettuccini is perfectly acceptable and increasingly the norm. But if you’re naming an Italian dish on an authentically styled menu, the proper plural makes all the difference.
