Let's say you are using a proper French dictionary (I use http://atilf.atilf.fr/). For an entry of any typical word, naturally you would find many abbreviations, e.g. “subst. masc.”, “p. ext”, etc. (I am taking the first word of that dictionary here). I would like to know whether there is a list of all these abbreviations expanded (either in general or for this dictionary in particular).
Thanks @Édouard for going through it. I think this link might be useful for those struggling like me http://www.wordreference.com/fr/Abbreviations-French.aspx
