I saw the question about this word, but it is more like an example of how not to use this word. From definitions I found on google, it looks like this word is used to describe someone who is not educated, or rude and unsophisticated.
But this sentence:
They are ignorant, please teach them
seems awkward to me (I never saw this usage, it is just an example). So this word is probably used for someone who is uneducated and rude/unsophisticated. Am I right? Because translator to my language shows synonyms for words like
uneducated, but from examples, it looks like it is not synonym with this word.
