Nature and Behaviour of Focussed and Focused

Focused acts like most English words. The word focus has two syllables. The stress is on the first. English usually does not double the last letter when the stress is on the first syllable. So focus becomes focused. It behaves like benefit and benefited.

Focussed breaks that habit. It doubles the “s,” as in bus and bussed. Writers did this to show a short vowel sound. It is a spelling choice, not a rule. The word still means the same. It acts as an adjective and a verb.

Why People Get Confused About Focussed or Focused

There are three main reasons.

• Two spellings look right. Both are real words.
• British and American English differ. Many words change across the sea, like colour and color.
• Doubling rules are messy. English sometimes doubles a letter and sometimes does not.

People think one must be wrong. In truth, one is just more common.

The Origin of Focus

Focus comes from Latin. The Latin word meant “hearth,” or the place where a fire burns. A hearth was the center of the home.

Later, scientists used the word for the point where light rays meet. This is the point where a lens makes a sharp image. English borrowed the word in the 1600s. First it was a noun. Then people began to use it as a verb.

When writers needed a past tense, they had two options. Some wrote focused. Others doubled the “s” and wrote focussed. Both spellings have been used for a long time. Over time, focused won most of the ground.

British vs American English

• US: focused, focusing
