  • A pejorative sense when used to criticize someone for not knowing something that is reasonably expected to be known.

Etymology

etymology 無知 is a Sino-Japanese compound formed from 無 meaning without and 知 meaning knowledge; its modern reading is むち (muchi) and the meaning stems from the combination of the two semantic components rather than a phonetic change.

Composition

  • 無: absence or negation
  • 知: knowledge, knowing
  • combined meaning: lack of knowledge, ignorance

Usage

Usage noun usage in formal and informal contexts; in formal writing it can appear as 無知の露呈 or 無知を指摘する; in everyday speech it is used to describe ignorance or lack of knowledge about a topic. Example phrases in Japanese include 無知を露呈する, 無知を恥じる, 彼はその分野の無知を認めた.
💡 Tips
Mnemonic: picture 無 as a big empty space and 知 as a bundle of knowledge; when you place them together, the space is filled with not-knowing, giving you the concept of 無知; the reading mukhi/muchi helps link the two kanji to memory.
