- Common Mistake 1: Misplacing stress: learners sometimes stress the second syllable or wobble between /ˈkwɑːr/ and /kwɔːˈtoʊ/. Correction: fix to primary stress on first syllable with a clear /ˈkwɑːr/ (US) or /ˈkwɔː/ (UK) and keep the second syllable light. - Common Mistake 2: Incorrect vowel quality in first syllable: US often uses /ɑː/ or /ɔː/; ensure you’re using an open back vowel rather than a lax /æ/ or /ɒ/. Correction: practice with minimal pairs to sharpen backness and length. - Common Mistake 3: Over-emphasizing the final /toʊ/ or mispronouncing /təʊ/; avoid a hard stop after the second syllable. Correction: end with a soft, unaspirated glide, almost a half-syllable when followed by a pause.
"The library catalog lists the ancient text as quarto, indicating its size and formatting."
"She referenced a quarto edition of the novella, which is notably larger than the pamphlet version."
"The cataloging rule assigns a separate entry for every quarto and folio in the collection."
You pronounce it as KWAR-toh with the stress on the first syllable. IPA: US ˈkwɑːr.toʊ, UK ˈkwɔː.təʊ, AU ˈkwɔː.təʊ. Begin with a rounded /k/ release, follow with /w/ + an open back vowel /ɑː/ or /ɔː/ depending on accent, then a clear /r/ (US rhotics may insert a linking /ɹ/ in some accents), and end with a light, unvoiced /t/ followed by a rounded /oʊ/ or /əʊ/.
The two most common errors are: 1) misplacing stress or mispronouncing the first syllable as a short /a/ sound (you should use /ɑː/ or /ɔː/ depending on accent); 2) conflating the second syllable with a hard /oʊ/ instead of a schwa or reduced vowel before the final /oʊ/ in US/UK patterns. Correction: maintain stable /ˈkwɑːr/ or /ˈkwɔː/ through the first two phonemes, then a precise /toʊ/ or /təʊ/ with a light final consonant, avoiding a heavy/dropped syllable. Practice with minimal pairs: kwart/o vs corto.
In US, you’ll hear /ˈkwɑːr.toʊ/ with rhoticity: the /r/ is pronounced and the final /oʊ/ lands as a diphthong. UK usually uses /ˈkwɔː.təʊ/, with a non-rhotic /r/ and a longer, rounded mid back vowel in the first syllable, and a clearer /əʊ/ at the end. Australian speakers often align with UK patterns but may compress the middle vowel slightly and retain rhoticity in careful speech; some speakers exhibit a subtle /ɹ/ in receptive contexts. All three share the initial /kw/ onset and a non-final schwa or reduced vowel in the second syllable depending on accent.
The tricky aspect is the non-phonemic linking nuance: in faster speech, English listeners may perceive a subtle /ɹ/ or /t/ tie across syllables, creating a near-diphthong in the second syllable. Additionally, the second syllable can be pronounced with a mid-centralized vowel or with a light schwa in British and Australian speech, which can surprise learners who expect a fully pronounced second syllable. Paying attention to the final /oʊ/ or /əʊ/ and the strength of the /r/ can help maintain natural rhythm.
The final vowel is typically a long rounded vowel in American English /oʊ/ and a clipped variant in British and Australian English /əʊ/. The key is not to over-emphasize the final vowel; keep it brisk and light to avoid dragging the word into a drawn-out ending. In careful speech, you’ll hear a full /oʊ/; in casual speech, a nearly silent or reduced vowel may occur before a following consonant.

US: rhotic /r/, fuller /ɑː/ or /ɔː/ depending on speaker. UK: non-rhotic; broader /ɔː/; final /təʊ/ or /toʊ/ with a crisp, shorter vowel. AU: closer to UK but with slight rhotic tendencies in careful speech; avoid over-aspiration. IPA references: US ˈkwɑːr.toʊ, UK ˈkwɔː.təʊ, AU ˈkwɔː.təʊ. Focus on tightening the second syllable and maintaining clean /t/ before the final vowel, not an extra syllable.
Quarto comes from the Latin quartus meaning “fourth” and historically referred to a size of a manuscript or book made by folding a full sheet of parchment or paper twice to create four leaves (eight pages). The term likely originated in medieval Latin scriptorium practices, evolving into the English bibliographic convention by the 15th–16th centuries. In printing, a quire was a group of leaves; a quarto was sized to accommodate a single fold, aligning with the four-part subdivision. Over time, quarto editions became standard for early modern books, especially literary and scholarly works, until the shift toward smaller formats (octavo, duodecimo) occurred in the 17th–18th centuries. The word remains primarily as a bibliographic descriptor rather than a semantic category, though it can also appear in contexts referencing a person’s name or title. First known use in English appears around the 15th century in library catalogs and colophons, with widespread usage in scholarly bibliographies thereafter.
