German for "the". Sounds like "duh", or "dah", so this would explain why "der" is used as "duh" in this day and age. Or maybe because it sounds funnier.

Deutsch für "the." Anwendung finden als ein männlich wörter.

"Der" is a German word used for "the." As with most old, European languages, there are sex tenses in German. Der, in this case, is masculine; pronounced much like the word, "dare." It's not pronounced as "dur," as many retarded ignoramouses claim.
