 Later, attempts were made to reconcile the two standards into "Samnorsk", or "Common Norwegian", although this never came to fruition.Bokmål, the written language of 80-90% of the Norwegian population, is based on Riksmål, although it differs in terms of genders, lexicon, counting system, a tendency to permit concrete noun endings in abstract situations and diphthongs versus single vowels.Riksmål was officially changed to Bokmål in 1929.
