Questions & Answers about Dit is een groot ruimtelijk probleem.
Why do neither groot nor ruimtelijk get an -e ending here?
Both are adjectives modifying the noun probleem, which is a het-word (het probleem). When a singular het-word is introduced by the indefinite article een, any adjectives preceding it drop their standard -e ending.
If I wanted to say "This large spatial problem", how would those adjective endings change?
You would say Dit grote ruimtelijke probleem. By using the demonstrative word dit instead of een, the noun phrase becomes definite. Definite singular het-words require their adjectives to take the -e ending.
How is the word ruimtelijk formed?
It is formed by adding the suffix -lijk to the noun ruimte (space), turning it into an adjective meaning "spatial". In Dutch, you will frequently encounter this word in the context of ruimtelijke ordening, which refers to urban planning or spatial planning.
