The correct spelling is "illiterate".
Illiterate means unable to read or write. It can also be used figuratively to describe someone who lacks knowledge or understanding in a particular area.
Here are some examples of how the word "illiterate" is used:
* "He was illiterate and had to rely on others to read letters for him."
* "The politician's speech was full of empty rhetoric, showing his illiteracy on economic issues."
It's important to use the correct spelling when communicating, as misspellings can be confusing and detract from the clarity of your message.
