IPA: /ˈɪɡnərənt/
KK: /ˈɪɡnərənt/
Not having knowledge or education about something.
He made an ignorant comment about the topic without understanding it.
Ignorant is formed from "ignorare" (meaning to not know) and the suffix "-ant" (indicating an agent or one who performs an action). The word describes someone who is in a state of not knowing or lacking knowledge.
Think of someone who 'does not know' ('ignorare') something — that's why ignorant means lacking knowledge.
