Genius or Genious: Which Is Correct?
Updated · Which One Is Correct editorial team
Quick answer: When you ask yourself whether genius or genious is the right choice, the answer is clear and specific. The word genius is the correct spelling used to describe a person of remarkable intelligence or creative ability. The alternative spelling genious is incorrect and should always be avoided in formal writing. Remember that the letter u belongs in the middle of the word, not the end, to ensure your message remains professional and accurate.
The Short Answer
People often confuse these words because the letters u and s look similar when typed quickly, leading to accidental errors in digital communication. Additionally, the suffix -ous in other adjectives like famous or generous might trick writers into thinking the word genius should end in s instead of u.
