Bommert: Danish Grammar Quiz

Every sentence in Bommert has one small mistake in Danish, or none at all. Find it, tap it, and choose the right fix.

The mistakes are the ones people really make: the present tense -r (nutids-r), ligge or lægge, der or som, at or og, en or et, compound words written apart, and spelling that trips people up. It works for people learning Danish and for native speakers who want to sharpen their writing.

HOW IT WORKS
Tap the word that is wrong, then pick the correction from a few options. If the sentence is fine, say so: about one sentence in six has no mistake at all, so guessing does not pay. Every answer comes with a short, plain explanation.

IT GROWS WITH YOU
The sentences get harder as you get better, from beginner slips to mistakes that catch out careful Danish writers. Every round of ten is a mix.
