'Der Däne' (the Dane) belongs to the N-declension. This means that the word takes the ending '-n' in all cases except the nominative singular. This is an important rule for many masculine nouns that refer to living beings.
Ich habe gestern mit dem Dänen gesprochen.
I spoke with the Dane yesterday.
The word 'Däne' (Dane) is part of a word family. It is derived from the country 'Dänemark' (Denmark) and is related to the adjective 'dänisch' (Danish).
Die dänische Flagge ist rot und weiß.

When you state a person's nationality like a profession or characteristic, you can leave out the article. The subject then stands with the verb 'sein' (to be).

Danish
'dänisch' and 'der Däne' both have to do with Denmark. But 'dänisch' is an adjective and describes things, people, culture, or language: 'ein dänisches Lied' (a Danish song), 'dänisches Essen' (Danish food). As a language, 'Dänisch' is capitalized. 'der Däne' is a noun and means a male person from Denmark. The words can be confused because in German you need different forms for language, origin, and a person. Practical tip: use 'dänisch' for qualities, and 'der Däne' for a man from Denmark.
