lah-EH-reh-oh, four distinct vowel sounds in a row, each one kept separate and pure. In IPA: /laˈɛ.re.o/. Stress falls on the second syllable, the open "eh."

l'aereo (m.) /laˈɛ.re.o/

Four syllables once the article elides in, la-e-re-o, with the stress on the second. Unlike "ciao," where vowels blend into one beat, these four vowels stay as four separate beats — a hiatus, not a diphthong.

Sound it out

"Aereo" packs four vowels into one word with no consonant separating two of them (a and e sit right next to each other), and the temptation is to smooth them into a glide the way English does with similar vowel pileups. Italian keeps each one distinct instead.

l'a The elided article "l'" flows straight into the a, a quick, open "lah" with no pause before the next vowel.

e An open, stressed "eh," as in "bet" — the loudest syllable in the word, and distinct from the a right before it, not blended into it.

re A short, unstressed "reh," with a single light tap on the r.

o A short, closed "oh" to close the word, said plainly with no glide.

The example, "L'aereo parte tra un'ora" (The plane leaves in an hour), shows two elisions in quick succession: "l'aereo" (lo + aereo) and "un'ora" (una + ora), both triggered because the following noun starts with a vowel. "Tra" here means "in" in the sense of a future time span ("in an hour" = an hour from now), distinct from "in," which marks location or a duration already underway.

"Un'ora" keeps its apostrophe because "ora" (hour) is feminine — "un'" (from "una") signals that gender, whereas the masculine elided article "un" before a vowel-initial noun never takes an apostrophe. It's a small spelling detail that tracks a real grammatical distinction.

Where English speakers slip

The vowel sequence a-e is the main hazard: English readers tend to smooth adjacent vowels into a single glide, producing something like "AIR-ee-oh," borrowing the sound of English prefixes like "aero-." In Italian, the a and e stay two fully separate syllables, with the stress landing squarely on the e, not blended together.

The second slip is dropping a syllable altogether under the pressure of so many vowels in a row, compressing the word to three beats instead of four. Each of the four vowels in "aereo" earns its own syllable, even though English instinct is to simplify vowel clusters wherever possible.
