Focuses vs. Focusses

The main difference is the number of s letters before -es.

Focuses:

f-o-c-u-s-e-s

Focusses:

f-o-c-u-s-s-e-s

The second spelling doubles the final s.

Feature	Focuses	Focusses
Meaning	To concentrates on something	To concentrates on something
Correct?	✅ Yes	✅ Yes
Common in American English	✅ Very common	Less common
Used in British English	✅ Yes	✅ Yes

A small grammar correction is important here: focuses means concentrates, not “to concentrates.” The base verb is focus, while focuses is used with he, she, it, or a singular noun.

Why Does Focusses Have Two S’s?

The spelling focusses follows a pattern used by some writers for verbs ending in -s.

The idea is that the final s of focus is retained and another s is added before -es:

focus + es → focuses

Both forms are found in standard English.

This is why dictionaries and style guides may show both forms, with different preferences depending on region or style.
