illiterately

An illiterate person can't read or write.

The word "illiterate" can sound harsh, but it's actually used pretty often to describe someone who hasn't had much education. It might seem like a bad thing, but many people use the term without thinking about it in a negative way. For example, when you're watching a news program and they mention that 30% of adults are illiterate, it usually means those people can't read or write very well. In some cases, it's because they didn't finish school or never went to school at all. But it might also be because someone got their education later in life, like when they moved to a new country where the language is different.
