Questions & Answers about Het weer is vandaag heel warm.
Why doesn't warm get an -e at the end here?
Because warm comes after the verb is to describe the weather, rather than standing directly in front of a noun. When an adjective is used this way, it never gets an -e ending.
Can I use erg instead of heel in this sentence?
Yes! You can absolutely say erg warm instead of heel warm. Both heel and erg mean "very" when placed before an adjective, and they are completely interchangeable in this context.
Why is vandaag put before heel warm instead of at the end of the sentence?
In Dutch, time words like vandaag (today) usually appear as early as possible in the sentence, right after the main verb. English puts "today" at the end, but Dutch prefers to establish the time early on.
