When I look up the word "inform" and check out its synonyms, I can see that the words apprise and impart are listed as a synonym of it, besides more informal words such as tell and communicate.
However, neither the word apprise nor the word impart is shown as synonyms of each other on the Oxford Dictionary, when I looked them up one by one. I am cognizant of they are formal words, however especially for this reason I would like to use them correctly in my writings.
Therefore,this made me enquire concerning the difference between them in terms of meaning.
