Questions & Answers about De vrouw is erg boos.
Does erg mean the same thing as heel here?
Yes. When used to modify an adjective, both erg and heel mean "very". You could also say De vrouw is heel boos and it would mean exactly the same thing.
Why doesn't boos get an extra -e at the end in this sentence?
Because it comes after the noun it describes, separated by the verb is. When an adjective is used this way (called a predicative adjective), it never gets an -e added to it. You would only add the -e if it came directly before the noun, like in de boze vrouw (the angry woman).
I thought erg meant "terrible" or "bad". Why does it mean "very" here?
Erg can be both an adjective and a modifier. When used on its own to describe a noun, it means "terrible" or "bad". But when placed right before another adjective like boos, it acts as a degree modifier that simply means "very".
If the subject was plural, would boos change to match it?
No! If the sentence was plural (De vrouwen zijn erg boos), the adjective boos still wouldn't change. Because it comes after the verb, it stays exactly the same whether the subject is singular, plural, a de word, or a het word.
