Usage
Plural word for genius The plural form of genius can be either geniuses or genii, pronounced [ jee-nee-ahy ], depending on the intended meaning of the word. Geniuses is much more commonly used. The plural forms of several other singular words that end in -us are also formed in this way, such as virus/viruses, callus/calluses, and status/statuses. Irregular plurals that are formed like genii, such as radius/radii or cactus/cacti, derive directly from their original pluralization in Latin. However, the standard English plural -es is often also acceptable for these terms, as in radiuses and cactuses.

Etymology
Origin of genius
First recorded in 1350–1400; Middle English, from Latin: “tutelary deity or genius of a person”; cf. genus
Explanation
Genius is an exceptional talent or skill, something above and beyond the norm. A genius is someone who possesses this brilliance, like a child prodigy who learned the piano at age 3 and played sold-out concerts by age 5. Genius comes from the Latin word of the same name, meaning "guardian deity or spirit which watches over each person from birth" or "innate ability." Your genius — your superior talent — at the game of chess could make you a world champion. Your amazing genius would also make you a genius. The word can be used more lightheartedly to describe a natural ability or flair for something. You may have a genius for putting together stylish outfits.
