Questions & Answers about Binnen één seconde was het scherm leeg.
Here binnen means within.
So Binnen één seconde means within one second. It gives a time limit: the result happened before one second had passed.
This is different from a literal physical meaning of binnen, which can also mean inside in other contexts.
Dutch uses één with accents when it clearly means the number one.
- een = a / an
- één = one
So:
- binnen een seconde can still be understood, but may look more neutral
- binnen één seconde emphasizes the number: within one single second
The accents help prevent confusion and often add emphasis.
Because after één, Dutch normally uses the singular noun.
- één seconde = one second
- twee seconden = two seconds
So the singular seconde is correct here.
