Learn Dutch: Ik heb geen woorden voor zulke ongelofelijke orkanen. - I have no words for such unbelievable hurricanes.

Zulke means "such" and is used before plural nouns like orkanen (hurricanes), as well as uncountable nouns. You would only use zo'n for a singular countable noun, like zo'n orkaan (such a hurricane).

Why does the adjective ongelofelijke get an -e at the end?

Adjectives almost always get an -e added to them when they come right before a noun. Because orkanen is a plural noun, the adjective modifying it must take this -e ending.

Why do we use geen instead of niet to say "no words"?

In Dutch, you use geen to negate nouns that are indefinite, meaning they don't have a specific word like "the", "this", or "my" in front of them. Since we are negating the general plural noun woorden (words), we must use geen.

The singular word for hurricane is orkaan. Why does the plural orkanen drop an a?
