"You need no postage stamp to send a postcard."

Translation: Du trenger intet frimerke for å sende et postkort.

[Hattedamen]

Jo, det gjør du!

[pertinaciousfox]

What's the difference between intet and ingen?

[ilyvion]

"intet" is the neuter form of "ingen."

[vtopphol]

This sounds archaic. I would rather say "Du trenger ingen frimerker".

[OsloBen]

Why is is the "for" here in this sentence?, why isnt å sende enough?

[ilyvion]

"For å" has the meaning of "in order to." Without the "for," this sentence makes no sense in Norwegian.
