Luxembourgish language
In German orthography, nouns and most words with the syntactical function of nouns are capitalised to make it easier for readers to determine the function of a word within a sentence ( – "On Friday I went shopping.";  – "One day he finally showed up.") This convention is almost unique to German today (shared perhaps only by the closely related Luxembourgish language and several insular dialects of the North Frisian language), but it was historically common in other languages such as Danish (which abolished the capitalization of nouns in 1948) and English.
