Please help me about this sentence:

Friday local time, sending a dense a black cloud as high as 9,000 meters and a flow of hot gases and rock down the mountainside into the ocean.

Why is the article 'a' used twice in the phrase a dense a black cloud? Please help me understand this.

  • Good for you, you found a typo. it should just be, "sending a dense black cloud..." – Jim Jun 1 '15 at 0:40
  • Actually, "a" is used 3 times. – Hot Licks Jun 1 '15 at 0:40

  • By the way, that is not a sentence. It has no subject. – Brian Hitchcock Jun 1 '15 at 6:34

This is simply a typing error. This should read:

..sending a dense, black cloud as high...

The comma after dense is optional.

  • "optional" as in unnecessary :) I vote to remove that comma! – Misha R Jun 23 '15 at 7:45
  • A dense, black cloud = a cloud that is both dense and black. A dense black cloud = a dense cloud that is black in color. Compare: a light blue shirt = a blue shirt that is light in color, not light and blue. – Yosef Baskin Jan 30 '17 at 22:08
