I have played around with plain tex for a while now and can't figure out how to get back to justified text after e.g. \raggedright. Can it really be that I have to use \raggedright in a group \begingroup\raggedright...\endgroup in order to restore justified text? There has to be a way to get back the original justifying.

edit: I could get something similar to justified texts by using

\spaceskip3pt plus 2pt minus 1pt

But this is not the original justifying.

    You can use \show\raggedright to have TeX stop and show what it is defined as. Commented Jul 8, 2018 at 7:25
  • @ShreevatsaR Nice thanks, I wasn't aware of it and checked plain.tex for its definition before.

Just revert the settings of \raggedright.

    +1. Using \begingroup and \endgroup to surround the ragged-right material doesn't seem to be such a bad idea after all... :-)

  • Indeed, but since I am learning, I am trying out things :P Why should I use plain tex nowadays? It's more trying to handle the basics, too.
