What does ø mean?
The letter o with stroke ø (capital Ø, Unicode name LATIN SMALL LETTER O WITH STROKE), often informally called slashed o, is a distinctive vowel letter in the Danish, Norwegian, Faroese, and Southern Sami alphabets. It originated in medieval Scandinavian manuscripts as a ligature of the letters o and e, which gradually stylized into a circle crossed by an oblique diagonal stroke.
Phonetically, ø represents close-mid or open-mid front rounded vowels (/ø/ and /œ/), directly corresponding to the Swedish, German, and Finnish letter ö (as in Danish købe, Norwegian snø, and smørrebrød). In mathematics and technical drawings, users must take care not to confuse the linguistic letter ø with the empty set symbol ∅ (U+2205) or the engineering diameter symbol ⌀ (U+2300), which are separate characters with distinct geometric dimensions. Type ø on Windows with Alt + 0248, or on a Mac with Option + O.
Common uses
- Danish and Norwegian city names and geography: København, Tromsø, Bodø
- Scandinavian food and culture: smørrebrød (open sandwich), øl (beer)
- Nordic personal names and authors: Søren Kierkegaard, Sigrid Undset
- Musical band branding (e.g. Twenty One Pilots stylization)
