Questions & Answers about De lengte, de breedte en de hoogte bepalen de grootte.
Why is it lengte with an 'e' instead of 'langte' from the adjective lang?
Unlike most adjectives that simply add the -te suffix (like hoog becoming hoogte), lang undergoes a vowel change to become lengte. This is a historical exception in Dutch, so you just have to memorize it.
Why does grootte have a double 't', while hoogte only has one?
The adjective groot already ends in a t. When you add the -te suffix to turn it into a noun, you keep both letters (groot + -te = grootte). This is important because it visually distinguishes the noun grootte (size) from the inflected adjective grote (large), even though they sound identical in speech.
How do you pronounce the dt in breedte?
It is pronounced exactly like a single 't' sound. The spelling preserves the d from the root adjective breed (wide) and adds the t from the -te suffix, but you do not pronounce the 'd' separately.
Notice how the sentence uses de for every dimension. Are all -te nouns de words?
