"There are two noun classes (genders) in Danish: common and neuter. All nouns are mostly arbitrarily divided into these two classes. The singular indefinite article (a/an in English) for common nouns is en and for neuter nouns is et. They are often informally called n-words and t-words."
I copied this from http://en.wikipedia.org/wiki/Danish_grammar. ☺
Oranges first came to Europe via Dutch traders and were called "appelsina" or "apple (from) China".
The pronounciation of "appelsinen" is misleading - the "i" should be stressed
