If someone is semiliterate, they can read and write a little, but not very well.
Being semiliterate is not as good as being fully literate, but it's better than not being able to read or write at all.
Examples:
He is semiliterate, so he can read some words.
She is semiliterate, but she wants to learn more.
The semiliterate man struggles with reading.
The cat is semiliterate and can only read its name.
The semiliterate dog tries to read the newspaper every day.
The semiliterate girl is learning to read and write at school.
