+# Norwegian
+
+Norwegian(is available for `pdftex`, `xetex`, and `luatex`. An example
+for `pdftex` with the UTF-8 encoding is:
+```tex
+\documentclass{book}
+
+\usepackage[norsk]{babel}
+\usepackage[T1]{fontenc}
+
+\begin{document}
+
+Alle menneske er fødde til fridom og med same menneskeverd og
+menneskerettar. Dei har fått fornuft og samvit og skal leve med
+kvarandre som brør.
+
+\end{document}
+```
+
+With `luatex` and `xetex` remove the line:
+```tex
+\usepackage[T1]{fontenc}
+```
+
+Nynorsk is also available. Just write instead:
+```tex
+\usepackage[nynorsk]{babel}
+```
+
+## Hyphenation
+
+A number of words (a few hundred) require adding a letter when
+hyphenated. In `pdftex` and `xetex` they must be marked explicitly with
+a shorthand, like `volleyba"llandslag` (‘volleyball-landslag’).
+
+With `luatex` no explicit markup is required, because they can be
+added to the exception list with:
+```tex
+\babelhyphenation[norsk]{vol-ley-ba{ll-}{l}{ll}ands-lag}
+```
+Here, the group `{ll-}{l}{ll}` is equivalente to a `\discretionary`.
+Remember you must add every word (like, say, ‘volleyballandslaget’).
+
+Alternatively, you may define a transform, which is more flexible, but
+less efficient. For example:
+```
+\babelposthyphenation{norsk}{ vol|ley|ba()l()lands|la }{
+ { no = l, pre = ll- }
+}
+```
+This rule matches the sequence of characters and hyphenation points in
+the second argument, which explains why the ending ‘g’ has not been
+included —without it, ‘volleyballandslaget’ is also matched.
+
+Furthermore, with transforms hyphenation points can by weighted with
+different penalties, too, as explained in [Non-standard hyphenation
+with
+luatex](https://latex3.github.io/babel/guides/non-standard-hyphenation-with-luatex.html).
+
+Feel free to contribute list a words requiring this feature.
