The Singular and Plural of Focus
The word “focus” originates from Latin, where it was used to mean “hearth” or “fireplace,” a central point in any home. In English, it has come to mean a point of concentration, clarity, or attention. The pluralization of “focus” follows two acceptable forms: “foci” (/ˈfoʊsaɪ/ or /ˈfoʊki/) and “focuses.” The use of “foci” is more common in formal, scientific, or technical contexts, especially when referring to points of convergence in fields like mathematics, optics, and geography. “Focuses,” on the other hand, is widely used in general contexts and follows the regular pattern of adding “-es” to the end of words ending in “s.”
