It depends on TeX distribution. If you use TeX Live, "kpsewhich
language.dat" tells you the location of the file. You can always make
a backup copy. Remember that in TeX Live any update by tlmgr may
restore the file to its default. You should red the manual where local
configuration files are described. If you use another TeX
distribution, you should read its manual.
