Providing little or no information; not helpful in giving details.
The report was uninformed and did not help us understand the situation better.
Uninformative → It is formed from "un-" (meaning not) and "informative" (from Latin "informare", meaning to shape or form an idea). The word "uninformative" means not providing useful information or lacking in informative content.
Think of 'not' ('un-') providing useful 'shaping of ideas' ('informative') — that's why uninformed means lacking useful information.
