A long narrow flag is a type of banner that is typically flown from a pole or mast. The term 'long narrow flag' can refer to three different types of banners: a STREAMER (8 letters), a PENNANT (7 letters), or a PENNON (6 letters). A STREAMER is a long, thin flag that is usually triangular in shape and has a tassel at the end. A PENNANT is a long, tapering flag with two points at the end. A PENNON is a long, narrow flag with a swallowtail at the end.
