Throughout this period, Danish was in contact with Low German, and many Low German loan words were introduced in this period. With the Protestant Reformation in 1536, Danish also became the language of religion, which sparked a new interest in using Danish as a literary language. Also in this period, Danish began to take on the linguistic traits that differentiate it from Swedish and Norwegian, such as the "stød", the voicing of many stop consonants, and the weakening of many final vowels to /e/.
