This question already has an answer here:

Where can I get a list of all Plain TeX macros. In the TeXbook, it is said that Plain TeX adds about 600 macros (to the ~300 TeX primitives). Where are they listed (with their documentation)?

    the texbook is the documentation, the full text of plain tex is in appendix B – David Carlisle Mar 21 '17 at 22:21
  • You are right. I did not have a copy of the texbook nearby when I wrote that question. If you make your comment an answer, I will accept it. – Gradient Mar 22 '17 at 0:03
  • @erreka: The linked question is about TeX primitives (e.g. this list), while this question is about (non-primitive) macros added by the plain format. (E.g. \quad, \nobreak, \centerline etc., which are macros added by plain, and you won't find them on the list of primitives.) – ShreevatsaR Mar 28 '17 at 15:31
  • @ShreevatsaR Maybe the question but not the answers. – Schweinebacke Mar 30 '17 at 5:50

The texbook is the documentation, the full text of plain tex is in appendix B

  • +1. Possibly worth adding, the source of plain.tex is also available on Knuth's site, on CTAN, and on your local TeX installation (kpsewhich plain), though of course without the documentation that is in Appendix B of the TeXbook. – ShreevatsaR Mar 28 '17 at 15:45

You'll find a capsule summary of commands, primitive and Plain, in chapter 13 of TeX for the Impatient; chapters 5-9 are more detailed descriptions of the primitives.
