Questions & Answers about Zo'n orkaan is heel extreem.
Why do we use zo'n here instead of zulke?
Orkaan is a singular, countable noun, and in English it translates to "such a hurricane". In Dutch, you use zo'n for singular nouns. You only use zulke (such) for plural nouns (like zulke orkanen) or uncountable nouns (like zulke regen - such rain).
Where does the word zo'n come from?
Zo'n is a contraction of zo een (so a / such a). While you can sometimes say or write zo een if you really want to emphasize the "one", zo'n is the standard, natural way to express "such a" in everyday Dutch.
Why doesn't the adjective extreem get an -e at the end here?
Adjectives only get an -e ending when they come directly before the noun they describe (as in een extreme orkaan). Because extreem comes after the verb is in this sentence, it stays in its basic dictionary form without the extra -e.
Could I use erg instead of heel to mean "very" in this sentence?
Yes, you could completely naturally say erg extreem. Both heel and erg are used to mean "very" and are largely interchangeable as adverbs in Dutch.
