Focusses and focuses are both correct forms of the verb focus. Focuses is the more common choice, especially in American English, while focusses is also accepted in British English.
Have you ever typed focusses and wondered whether your spelling checker was right to question it? This small spelling difference can make even confident writers stop and check.
I often see this problem in student essays, business writing, and online content. The confusion comes from the verb focus and the way English handles words ending in a single consonant. Some writers add another s, giving focusses. Others use focuses.
The good news is simple: both forms are acceptable. The choice mainly depends on the variety of English you use and the style you want to follow. Oxford lists both focuses and focusses as present-tense forms of focus.
In this guide, you will learn the difference between focusses or focuses, see clear examples, understand the spelling pattern, and learn which form is best for school, work, websites, and formal writing.
focusses or focuses – Quick Answer
Focuses and focusses are both correct spellings of the third-person singular present form of focus.
For example:
- The report focuses on climate change.
- The report focusses on climate change.
Both sentences are grammatically correct. Oxford lists both spellings for the verb.
However, focuses is usually the safer choice for a broad international audience. It is especially common in American English, while focusses is a recognized British English variant. Cambridge also lists the verb with both -s- and -ss- forms.
What does focus mean?
As a verb, focus means to give attention to a particular person, subject, or activity. It can also mean adjusting a camera, eye, or other device so that something can be seen clearly.
For example:
The lesson focuses on basic grammar.
Here, focuses means “gives attention to.”
The Origin / Background of focusses or focuses
The spelling difference is not caused by a difference in meaning. Both forms come from the same verb: focus.
The word focus comes from Latin focus, meaning “hearth” or “fireplace.” Over time, the word developed a more specialized meaning connected with a central point. English later used focus for a central point of attention and for the point where light rays meet.
Today, focus has several common meanings. It can describe attention, a central subject, or the adjustment of a camera or optical device. Cambridge gives examples of all these uses.
The spelling issue appears when English speakers form the third-person singular:
focus → focuses
Some varieties and style traditions also use:
focus → focusses
Oxford records both forms, along with focused/focussed and focusing/focussing.
So, focusses is not simply a misspelling. It is a valid variant.
