What Does Genius Mean?

The word is used in several contexts, including science, art, mathematics, music, and everyday problem-solving.
Examples of Genius in a Sentence

Why Is Genius Correct and Genious Incorrect?
The standard spelling is genius, not genious. The word comes through Latin genius, which referred to a spirit associated with a person or place and later developed additional meanings related to natural ability and exceptional talent.
The spelling genious incorrectly adds an o before the final u sound.
Unlike words such as curious and serious, which end in -ious, genius does not follow that spelling pattern.
A useful way to remember the difference is:
Genius = G-E-N-I-U-S
There is no o between the i and u.
