The word focus comes from the Latin word “focus,” meaning center or point of attention. It originally referred to the point where light rays meet in optics.
Over time, the word became a verb: to focus, meaning to concentrate or direct attention. When adding ing, different spelling rules appeared.
In British English, writers sometimes double the consonant (focussing) following older spelling patterns. In American English, the simpler form focusing became standard.
