anthem is also a song...

Not every song is twerking material. The National anthem is sung, which is a characteristic of a song.

Yes dear I understand it is sung so it has the characteristics of a song. It just sounds a bit under valued as a whole country's national anthem to be called a song. But that's not my business.

I don't see how that could under value anything.. Who cares if you refer to it as a song OR an anthem?

An anthem is a TYPE of song. Definition from vocabulary.com: Rousing, reverential, sometimes even revolutionary, an anthem is a song that represents the ideals of a group of people. Anthem comes from Old English antefn. The original word meant a song sung antiphonally, or in turns by two groups of singers. Today, anthem has little to do with the way the vocals are arranged and more to do with the content of the message. When a group of people sing an anthem, whether it’s the national anthem, or the anthem of your third-grader’s beetle-collecting club, they express their devotion to a cause they identify with.

How would one pronounce antefn?

I read it as "anti-fin"

Would He get a boner from a third graders beetle club anthem to?
