l'autunno (m.) /auˈtunno/

Three syllables, au, tun, and no, with real weight on the middle one. The "au" isn't two vowels said separately, it's one gliding sound, closer to English "ow" than to "ah-oo."

Sound it out

The tricky part isn't the spelling, it's timing: that opening "au" needs to move fast as a single glide, and the "nn" in the middle needs to slow down and linger. English does the opposite on both counts, which is exactly what trips learners up.

au One gliding sound, like the "ow" in "cow," not two separate vowels "ah" then "oo."

tu A crisp, stressed "too", the loudest and longest syllable in the word.

nn A genuinely doubled n, held noticeably longer than the single n in an English word like "sunny."

o A short, closed "oh" at the very end, fully pronounced rather than swallowed.

"In autunno cadono le foglie" drops the article after "in" entirely, the way Italian handles all four seasons (in autunno, in inverno, in estate, though "in primavera" too). English needs "in the autumn" or at least "in autumn" with no article either way, so the pattern lines up here, but the habit is worth noting because Italian generally uses definite articles far more freely than English does elsewhere.

The dictionary form carries the article, l'autunno, because Italian nouns are conventionally cited with their article to show gender at a glance, autunno being masculine. Notice the elision, l' rather than lo, because the noun starts with a vowel.

Where English speakers slip

The most common mistake is under-doubling the n, saying something closer to a single-n word. That distinction is not decorative in Italian: "sono" (I am) and "sonno" (sleep) are a genuine minimal pair separated only by consonant length, so treating double n as just a spelling quirk can make words genuinely ambiguous.

The second slip is stretching "au" into two full beats, "ah-oo-TOON-no," the way English readers instinctively sound out every vowel letter on its own. In Italian, "au" moves as a single quick glide into the stressed syllable, not as two separate vowel sounds.
