This question already has an answer here:
During the paper writing, a question came up into my mind: can abbreviations be used in these articles?
There are at least 2 kinds of abbreviations, one is the so-called terminologies(or jargons?) which are too verbose for us to write all the alphabeta in the words every time. Though some of them have already been well-known in daily life(e.g., MP3, PDF), for others we are told to use the full name of the phrase and add the abbreviation in a parenthesis as its first occurrence and then use them in the following paragraphs.
The other group is about those abbreviations that are more commonly used in informal situations, such "a.k.a", "e.g.".
Though several of them have already been used in a number of papers, like "e.g.", "et al", "etc", "i.e.", most of the cases I hesitate to use them in the papers or other academic articles. Is it suggested not to use them? Here are a few that I can think of.
a.k.a. don't doesn't mustn't won't
