O with a Macron (Ō) – Typing, Pronunciation, and Usage
Few things trip up a writer quite like a missing macron. You know you need the long “o” sound for Māori words like Māori itself, but where exactly is that key on your keyboard? This guide walks through exactly what ō is, how to type it on any device, and why it matters for languages like Māori and Hawaiian.

What is ō?
Four key facts, one pattern: the macron turns a short vowel into a long one, and that difference changes meaning. In Māori, keke (cake) and kēkē (armpit) are distinguished by macrons — so accuracy matters.
How is ō defined in Unicode?
- Uppercase Ō: U+014C
- Lowercase ō: U+014D
- The character is part of the Latin Extended-A block (Em Rule editorial resource)
Which languages use ō?
- Māori (New Zealand): Essential for correct spelling and pronunciation (Kupu o te Rā language resource)
- Hawaiian: Used in kōlea (golden plover) and other words to mark long vowels
- Other Polynesian languages and romanisation systems (Hepburn Japanese, Pinyin Chinese)
The implication: ō is not a typographic flourish — it carries meaning. Omitting it can turn Māori into maori, which some speakers consider disrespectful.
How do you type an O with a macron?
Six methods, one challenge: most people don’t know the shortcut. Here are the reliable ways across platforms.
How to type ō on Windows?
- Alt code: Hold Alt and type 014D (lowercase) or 014C (uppercase) on the numeric keypad (Em Rule editorial resource)
- Māori keyboard: Add the English (New Zealand) – Māori layout. Press the tilde key (
`) then o to get ō (Kupu o te Rā language resource) - Unicode input in Word: Type 014D and press Alt+X (Em Rule editorial resource)
- Character Map: Open Character Map, select ō, and copy (Ara Institute PDF guide)
How to type ō on Mac?
- Māori keyboard layout: Hold Option (
⌥) and press o to get ō (Kupu o te Rā language resource) - Alternative: Press Option + ` then o (dead-key method)
How to type ō on mobile?
- iOS/Android: Long press the O key on the soft keyboard — a popup with accented options appears. Slide to select ō.
- On Android, install the Gboard app and enable the Māori language pack for persistent macron keys.
How to type ō using alt codes?
- Alt+014D works in most Windows applications that support Unicode.
- For uppercase Ō, use Alt+014C.
- Make sure Num Lock is on and use the numeric keypad — the top-row number keys won’t trigger the code (Em Rule editorial resource).
For anyone working with te reo Māori, a missing macron is more than a formatting error — it’s a change in meaning. The Māori Language Commission recommends always using the correct character, not a substitute like oo.
The pattern across all platforms: once you learn the shortcut, typing ō becomes as natural as typing any other letter.
How do you spell ō?
Two frequent confusions, one resolution: ō is a single character, not two letters.
What is the correct spelling of ō?
- Ō is a single character: O with a macron (a horizontal line above the letter).
- In digital text, it must be typed as one Unicode code point (U+014D / U+014C), not as O followed by a combining macron (though that works too).
Is ō the same as ó?
- No. ō uses a macron (¯), ó uses an acute accent (´).
- In Māori, the macron indicates a long vowel; the acute accent is not used.
- In Spanish and Portuguese, ó represents a different vowel sound entirely.
The pattern: diacritics are not interchangeable. Using the wrong one may render a word unintelligible.
How to pronounce ō?
Two language families, one principle: the macron lengthens the vowel.
What is the English pronunciation of ō?
- When borrowed from Māori, English speakers typically say the long o as in “go” (/oʊ/).
- Many loanwords retain the long sound, e.g., Māori is often pronounced “Mow-ree” (rhyming with “cow-ree”).
How does Māori pronounce ō?
- In te reo Māori, ō is a pure long vowel /oː/ — hold the “o” sound approximately twice as long as the short o (Kupu o te Rā language resource).
- Place your tongue as for a short “o” but sustain it. Think of the difference between “pot” (short) and “paw” (long) — that’s the length contrast.
Learning to hear and produce vowel length is hard for English speakers, but it’s essential for Māori comprehension. The Te Whanake series offers audio resources to practice.
The catch: English speakers tend to conflate vowel quality with vowel length, but Māori relies purely on duration.
Which languages use the ō character?
Three major contexts, one thread: they all use the macron to mark a long vowel.
What countries use ō?
- New Zealand (Māori) — the character is official in the Māori orthography.
- Hawaii (USA) — used in the Hawaiian language for words like Āina (land).
- Romanisations — Hepburn romanisation of Japanese uses ō for long ‘o’ (e.g., Tōkyō). Pinyin uses it for the first tone of the ‘o’ vowel.
Is ō used in Hawaiian?
- Yes. The Hawaiian alphabet uses the macron (called kahakō) to lengthen vowels. For example, kōlea (golden plover) would be unrecognisable without it.
Why this matters: digital support for ō isn’t just a typography issue — it’s a question of language preservation. The more seamlessly users can type macrons, the more accurately indigenous languages are represented online.
What we know and what’s still unclear
Confirmed facts
- Ō is a Latin letter with a macron, encoded in Unicode since version 1.1 (Em Rule editorial resource)
- In Māori, a macron (tohutō) transforms the vowel length and can change meaning (Kupu o te Rā language resource)
- Alt codes 014C/014D work on Windows; Option+o works on Mac with Māori keyboard layout (Em Rule editorial resource, Kupu o te Rā language resource)
- Mobile devices support long-press to access ō on most modern keyboards
What remains unclear
- Whether all mobile keyboards (especially older or non-English models) include ō in the long-press menu
- The exact pronunciation length in some regional dialects of Māori
“A macron (tohutō) is a line above a vowel in te reo Māori indicating a long vowel sound, such as in ‘ō’.”
Kupu o te Rā (Māori language learning resource)
“In Māori, ‘ō’ represents a long ‘o’ sound, pronounced longer than the short ‘o’.”
Em Rule (New Zealand editorial resource)
Frequently asked questions
What is the difference between ō and ô?
Ō uses a macron (horizontal line), indicating a long vowel. Ô uses a circumflex, which often indicates a change in vowel quality (e.g., in French). They are not interchangeable.
Can I use ō in English?
Only in loanwords from Māori, Hawaiian, or romanised languages. In standard English, the long o is not marked with a macron.
How to type ō on Android?
Long press the O key on the default keyboard (Gboard or Samsung Keyboard). If ō doesn’t appear, install the Māori language pack via Gboard settings.
What does ō mean in math?
In mathematics, ō is not a standard symbol. The macron is sometimes used in linguistic notation, not in equations.
How to type ō in Microsoft Word?
Use the Unicode shortcut: type 014D then press Alt+X. Or use Insert > Symbol, find Latin Small Letter O with Macron.
Is ō the same as oo?
No. ō is a single character representing a long vowel. “oo” is two separate letters and may have a different pronunciation (e.g., “boot” vs “boat”). In Māori, writing “Maaori” instead of “Māori” is non-standard.
How to copy ō from this page?
Select the character: ō (lowercase) or Ō (uppercase). Right-click and copy, or press Ctrl+C. Then paste into your document.
For anyone working with te reo Māori, Hawaiian, or romanised East Asian languages, the ability to type ō accurately isn’t a luxury — it’s a necessity. The tools are already built into your operating system; the only missing piece is knowing where to look. Adopt the Māori keyboard layout today, and you’ll never fumble for a macron again.
