Where “o.” sits in German frequency

o.ranks outside the top 100,000 German headwords, in the long tail of specialist, archaic, or seldom-used vocabulary, exactly the territory where a reader stops mid-sentence to double-check spelling.

Beyond rank #100,000. Source: FrequencyWords open word-frequency list.

Rare enough to double-check

o. is uncommon German outside the top frequency list, classed as anabbreviation. Rarity is why readers land here mid-draft. 3 senses are on record.

o. doesn't appear in our generated misspelling index, and the word's spelling is regular enough that our generator found nothing worth flagging. This entry stands alone in our confusable dataset, a sign it's visually distinctive enough not to be mixed up with another word.

This headword's origin isn't recorded in our source data, so its spelling is easiest explained by how it's pronounced rather than where it came from. The correct German form is o., spelled O-..
