How to Spell and Pronounce “Genius”
Correct spelling
The correct spelling is:
Genius
It is always written with -ius, not -ious.
Pronunciation
IPA: /ˈdʒiː.ni.əs/
Simple pronunciation: JEE-nee-us
Although the ending sounds similar to some words ending in -ious, the spelling remains genius.
What Does “Genius” Mean?

Genius is a noun with its own spelling, and the ending -ious is never used.
