What does focussed mean?
'Focussed' is the British-style spelling of 'focused', describing either the past-tense action of directing something — one's attention, a lens, or an effort — toward a single point, or the resulting state of being concentrated and free from distraction. A focussed person works with clarity and purpose, filtering out competing demands; a focussed camera produces a sharp image. The underlying word traces to the Latin 'focus', meaning hearth, which seventeenth-century scientists adopted to describe the point where light rays meet. Today 'focussed' carries connotations of discipline, intensity, and effectiveness — it appears in phrases like 'stay focussed' and 'laser-focussed'. Writers should note that 'focused', with a single s, is now the dominant spelling in both American and much contemporary British usage, making 'focussed' an accepted but increasingly old-fashioned variant of exactly the same word.
Adjusted or directed something, such as a lens or one's attention, so as to concentrate on a single clear point.
"She focussed the binoculars on the distant ridge."
British-style spelling; 'focused' is now standard in most contexts.
Concentrated and undistracted; directed clearly toward one goal or subject.
"A focussed athlete, he trained through the winter without complaint."
The word 'focus' began life as a Latin term for a domestic hearth — the fireplace at the centre of a home — before optics borrowed it to mean the point where light rays converge.

Etymology of focussed
The root word 'focus' comes from Latin, where it originally meant a hearth or fireplace — the warm centre of a Roman home. In the early seventeenth century astronomers and opticians, notably following Kepler's work on lenses, borrowed the term to name the points where light rays converge, and later writers applied it metaphorically to concentrated attention. The double-s spelling 'focussed' arose in Britain as a conventional way of signalling that the second syllable is short rather than long, and it persists chiefly as a British variant alongside the now more common 'focused'. Related terms such as 'focal' and 'focalize' descend from the same Latin source.

How focussed is actually used
The double-s form 'focussed' is a long-standing British variant; Oxford dictionaries historically favoured it, though most modern British publishers now also use 'focused'. In formal writing aimed at international audiences, 'focused' is safer. The verb itself derives from Latin focus ('hearth'), adopted into optical science in the 17th century.
Easily confused with focussed
'Focused' is the standard single-s spelling preferred in American English and increasingly worldwide, while 'focussed' with double s is an accepted but less common British variant of the same word.
