Standardised grammar format
This is a modified version of xain1112's "Standardised Grammar Format" that was in the format of a PDF file, and had duplicate sections for "Writing system/Orthography" and such.
"It’s a frequent problem in the community that we don’t know the exact way to organize a grammar. I’ve taken the liberty of going through sixeen grammar books from different languages and from different years (some were typewritten) and compared the tables of contents in order to make a somewhat consistent format of organization."
This grammar format was made by analysing the following languages (some are conlangs): Arapaho, Blackfoot, Choctaw, Chrau, Esperanto, Hawaiian, Hindi, Ithkuil, Japanese, Kelen, Lakota, Mam, Okuna, Tagalog, Tariana, Vietnamese. The outline includes everything found in all the grammars; just use what you have in your language.
