The Origin of Focusses or Focuses
The word “focus” comes from Latin, meaning “hearth” or “fireplace”, which later evolved to mean the central point of attention.
Its English usage dates back to the 17th century when scientists like Johannes Kepler began using it in optics and astronomy.
The pluralization rule created the difference:
- American English simplified it to focuses, following a general “add -es” pattern for words ending in -s.
- British English preserved focusses as an alternative, applying the classical Latin-inspired spelling, which some writers still prefer for literary or formal contexts.
Over time, focuses became the dominant form in both spoken and written English, while focusses remained a valid but less common British variant.
