Questions & Answers about De aarde is niet plat.

Why does niet go immediately before plat?
In Dutch main clauses, niet is generally placed towards the end of the sentence. However, when it directly negates a specific adjective like plat (flat), it steps in right before that adjective. In this case, it works exactly like "not flat" in English.
Could I use geen instead of niet to say "not flat"?
No, because plat is an adjective (a describing word). You only use geen to negate nouns, which are people, places, or things (for example, saying "not a planet" becomes geen planeet). To negate adjectives, always use niet.
Why isn't aarde capitalized? We often capitalize "Earth" in English.
In Dutch, aarde is usually written with a lowercase letter when referring to the world in general or the ground beneath our feet. It is only capitalized (Aarde) in scientific contexts when listed alongside other planets like Mars or Jupiter.
