I want to align the last word of a paragraph to the right like this example from The TeXbook.

This works great with a justified paragraph, but fails with a raggedright paragraph.

In case it's relevant, my specific example in the MWE example below includes a slightly more complicated paragraph setup for typesetting psalms based on code from this answer.

There are two issues with my current set up.

1. The second to last word in the paragraph wraps on to the last line even when there is space for it on the previous line.


2. The last word of the paragraph (Selah) is not set flush right.

I also want to avoid hyphenation.

Looks like you can slightly modify the scripture_selah definition. I added the hspace*{0.025textwidth} just to make sure there is some extra space, so that Selah is padded and not immediately flush (if there is enough space, e.g. with him.').

cs_new:Nn scripture_selah:

  {

    {

      unskip

      hfil

      penalty 50

      hbox:n {}

      nobreak

      hspace*{fill}

      scripture_format_selah:n { hspace*{0.025textwidth}Selah }

      parfillskip = 0pt

      finalhyphendemerits = 0

      endgraf

      skip_vertical:n { -baselineskip }

      leavevmode

    }

  }

This works in the particular example that you provided. I am not sure if this will robustly work in every situation that you will be using it in.
