In comments I have added the words from the column "Meaning"
in "The TeXbook", chapter 7, page 37:

But above you have defined \char_make_other_char.
In general I think, where Knuth has written "xy character"
the word "character" could be omitted, because it is already
present as first compound of the macro. Also it would make
the macro name a little shorter. In part you have done it already:
\char_make_escape
\char_make_ignore
\char_make_comment
\char_make_invalid
but
==> \char_make_other
==> \char_make_active
