a person who does not have much knowledge 无知识的人 Word Originlate 16th cent. (the declarationof a grand jury about an accusation/claim which they considered to be backed by insufficient evidence to bring before a normal jury): Latin, literally ‘we do not know’ (in legal use ‘we take no notice of it’), from ignorare ‘not know, ignore’, from in- ‘not’ + gno-, a base meaning ‘know’. The modern sense may derive from the name of a character in George Ruggle's Ignoramus (1615), a satirical comedy exposing lawyers' ignorance.
