uninformed
UK: ˌʌnɪnˈfɔːmd | US: ˌʌnɪnˈfɔːrmd
adj. lacking knowledge or awareness about a particular subject
adj. not based on adequate information or research
The word "uninformed" combines the prefix "un-" (meaning "not"), the prefix "in-" (meaning "into"), the root "form" (from Latin "forma," meaning "shape" or "structure"), and the suffix "-ed" (forming adjectives). Originally, "inform" meant "to shape or train the mind," evolving into "to provide knowledge." "Uninformed" thus literally means "not shaped by knowledge," reflecting a lack of awareness or education.
